High score bounty! Something about calling sick for a headache

Skipping class? Ouch. Not good!

If you don't say that you have a tumor in your brain, you have to go for X-rays, chemotherapy, lasers** and so on.

Headaches are generally neurological and need to be watched for migraines. Stomach pain, possibly caused by cold.

It is recommended that you go to the hospital for a brain CT scan, the main reason is that the symptoms are not very obvious. A little more would be nice.

You should go to the hospital for a check-up as soon as possible, preferably when you have it done. It's a little more obvious to look up this way.

You can't do it with software, do you want to change your phone? Why bother, drop water on the motherboard, don't wet the waterproof sign, but not insurance, mobile phone repair masters are to detect whether it is man-made damage, they have already encountered these problems when they buy mobile phones, and they are afraid that you will not be able to do it, if you do this, people will directly come up with evidence, and in the end the phone will be broken and not replaced with a new phone, so you will lose yourself.

Not equal, not equal. 2).

But a2-a1=3;a3-a2=4；a4-a3=5 into equal differences. The first term a2-a1=3, tolerance = 1, an-a(n-1)=3+1[(n-1)-1]=n+, i.e., an=a(n-1)+n+1. continuous recursion, a(n-1)-a(n-2)=n; ...； a2=a1+3。

Accumulation, an=3+[(n-1)(n+1)] 2]=(n2+3n+2) 2, i.e., an=(n+1)(n+2) 2.

an=1+2+3...n+1=(n+1)(n+2)/2

If I remember correctly, it should be the difference-by-difference method, adding each term together, and the general formula an-an-1=n+1

This is love, this is marriage.

Plato once asked his teacher what love was, and his teacher told him to go to the cornfield first, and pick the largest and most luxuriant corn tree in the whole cornfield, during which he could only pick it once, and he could only walk forward, not turn back, so Plato did as the teacher said, and walked out of the cornfield empty-handed. The teacher asked him why he couldn't pick it, and he said, "Because I can only pick it once, and I can't go back, even if I see a big and golden one, because I don't know if there is a better one in front of me, so I didn't pick it, and when I walked to the front, I found that it was not as good as what I saw before, and it turned out that the largest and most golden corn in the corn field had long been missed, so I didn't pick anything."

The teacher said, "This is love." ”�

Another day, Plato asked the teacher what marriage was, and his teacher told him to go into the cornfield, and still pick the largest and most luxuriant corn tree in the whole cornfield, and in the meantime he could only cut down one, and the same could only go forward, and could not turn back, so Plato did as the teacher said, and this time he came back with an ordinary corn tree, and he said: "With the last experience, when I had gone to most of the distance and was empty-handed, I saw that this tree was not bad, so I cut it down, so that I would not miss anything and bring it out." The teacher said

That's what marriage is. ”
