Holding a math book, she pointed to one of the above questions and said shyly:

"monitor, I didn't understand the teacher's question in math class.

At that time, no one else said anything. I'm afraid of wasting everyone's time, so I have no good intention to ask. If it's convenient, can you tell me again? "

"Yes Yan Xi white thick eyebrows pick slightly, floating in the heart a little surprised.

What happened today? So many people stopped him. It's enough to borrow notes. There are still problems.

At noon, everyone will rush to the canteen. Usually few people will ask questions at this time.

I always feel It seems to be intentional.

However, the young handsome face, did not bring out the doubt, is still amiable.

He lowered his eyes slightly, and his dim sight swept over the pages. Then, he explained in a soft voice:

"this question is mainly about the comprehensive application of the arithmetic sequence and the equal ratio sequence.

To find Sn, we must first find the general term formula of the sequence.

In fact, an can be regarded as the sum of the first n terms of an equal ratio sequence with the first term of 1 and the common ratio of 3

In this way, we have the final answer. I don't know. Have I made it clear. "

The girl nodded: "speak super clear, hard monitor."

Tut Tut, the monitor is the monitor, EQ is not generally high, speech super level. It's not "do you understand?" it's "I don't know if I've made it clear.". After listening, I feel very comfortable.

"It's OK."

Yan Xibai out of the classroom, has been waiting at the door of Li Hu, immediately consciously follow behind.

The canteen of No.3 middle school is allocated according to the school year. High school students, generally eat in the second canteen.

In the canteen, there is no aunt to play dishes, it's all buffet.

A nutritionist was hired to match the recipes every day. There are also famous chefs who cook nutritious and delicious dishes.

As soon as the teenager approached the second canteen, he heard someone say, "here it is, here it is."

He was slightly stunned and went on for two steps. Just across the threshold of the canteen, a large group of people rushed over.

At the foot of Yan Xibai, his eyes suddenly narrowed. Instinctively switch to a state of general alert.

The next second, I found that about half of them were students from Class 3. The rest are from other classes this year.

"Happy Birthday to you..."

They clapped their hands and sang a birthday song.

Several students from other classes also gathered around the crowd, stretching their necks to watch the fun.

Seeing this, Yan Xibai's expression became loose, and then he took off his guard.

At the end of the song, Shen Chao, vice president of the team, came out from behind the crowd with a delicate cake in his hand.

No wonder they were sneaky just now. He also deliberately found two people and dragged him in the classroom. It turned out that it was to prepare these.

Young people hook up the corners of their lips and their eyes twinkle. Although the heart has no waves, but put out a surprise appearance: "thank you all."

They put a lot of thought into it, just to surprise him. Well, I'm happy to show them. It's not hard work. There's no need to spoil the fun of others.

"Make a wish Leng Rong, a member of the learning committee, suggested.

"Good." Yan Xibai nodded slightly, closed his eyes like a stream, and after ten seconds of silence, he blew out the candle with his classmates.

"Monitor, what did you wish for?" One student asked curiously.

Next to the students waved: "this can not be said, or it will not work."

Yan Xi's eyelashes blinked: "OK, then don't say. I'm going to try and see if it can be done next. "

Yes, it can't be said. Because just now, he didn't make a wish at all.

Any success must be achieved by hard work. Making a wish is a spiritual sustenance.

If the cake, said at will can achieve, that is not chaos?

For example, a vowed to marry B, and B vowed to marry C. how did it end? Have three people been together?

Then, the students gave presents. The young man took it with his own hands and expressed his thanks one by one.

Finally, he gave it to the bodyguard Li Hu and told him to keep it properly. After school, take everything back.

It was a great relief to see that he valued the gift very much.

When cutting the cake, Yan Xibai said sincerely:

"there will be a small birthday party at my home at seven o'clock tonight. Some relatives and friends want to take this opportunity to get together.

If it's all right, you can come and play. "

"Really? Great The students cheered as soon as they heard it.

The scale of the birthday party held by the Yan family is certainly not small. The people in this school are not all aristocrats. It's rare to be invited. Who doesn't want to see it?Shen Chao patted his chest and assured him, "don't worry, we will arrive."

"Yes, I've got something to do with it." Lengrong immediately echoed.

Their monitor is quick and resolute in dealing with affairs. He is vigorous in handling affairs, and has great momentum and dignity. They are very excellent and can not pick out any shortcomings. So, everyone is very convinced.

However, he seldom takes part in group activities after class. I never saw him, and anyone in the class, who was closer to the others.

In school, Yan Xibai's every move is easy-going and low-key. He's nice to everyone, completely the same. When others encounter difficulties, he will take the initiative to half busy. Such people are naturally very popular.

As the eldest grandson of Yan's group and the first successor of the family business, he could have done whatever he wanted, but he never pretended to be forced.

Every month, Yan Xibai can easily win the first prize.

Sometimes, everyone makes a fuss for the monitor to treat. He would have someone prepare the voucher, put it in an envelope and distribute it to everyone. All the coupons are from high-end restaurants.

Although he could not attend the party in person because of his busy work, he was always generous and generous, and there was nothing else to say.

This time, it is a rare opportunity.

Therefore, girls are thinking about what kind of clothes to wear and attend. Boys are looking forward to, when the time will see, what kind of grand scene.

Some people secretly speculate whether there will be popular stars and singers present. Also consider whether or not to bring a notebook, in order to find their signature as a souvenir.

Anyway, you have to fully charge your phone. Then, take photos of the whole birthday party and come back to make friends.

In the afternoon, after the second class, Li Bao came into the classroom.

Just now, his brother has gone back. In the afternoon, he was on duty, responsible for the safety of Yan Xibai.

Li Bao walked to the little master, whispered a few words, and turned out of the classroom.

Yan Xibai sat in his seat and pondered for a moment. After that, he took out his mobile phone and pressed several times, and sent a text message to the driver:

you can take time to go to Qingshui Road, the one we visited yesterday.

Then tell Qingzhu that the cat has been saved and ask her if she wants to keep it.

If she wants, and if grandma Yu doesn't object, she can send it to her tomorrow.
