37 how to calculate the next period of the flat yard three in two.

Summary. Dear, this law is divided according to the number of digits. What is the law of 9-49-14-45-19-41-24-37-29-33.

Dear, this law is divided according to the number of digits. 

We look at the odd digits of this column of numbers, that is, 9-14-19-24-29, which can be found to be 5 times larger than the previous number.

However, if we look at the even digits of this column of data, that is, 49-45-41-37-33, you will find that the latter number is 4 smaller than the previous number of the first friend. Celery is sold

The original question should be: 4 3-7 12+9 20-11 30+13 424 3-7 12+9 20-11 30+12 42=(1+1 3)-(1 3+1 Wei Mengchai 4)+(1 4+1 5)-(1 5+1 6)+(1 6+1 7)=1+1 3-1 3-1 4+1 4+1 5-1 Zhilian 5-1 6+1 6+1 7=1+1 Finger 7=1 and 1 7

This is summed by a series of equal differences, and two adjacent items are first combined to form an equal difference series, and the formula is calculated according to the equal difference series.

The original formula is equal to 5+13+21+. 77=(77+5)*10 2=82*5=410 You can also think of it this way, the original formula is equal to (4+8+12+. 40)+(filial piety 1+5+9+.

37) The state envy is separated from the book to be cautious and shoot, or the eyes are better, note (1+5+9+. 37）=（4+8+12+。。40)-10*3, the same result can be found.

First of all, it is found that simple operations can be performed by changing the order of the quiet orange scatter by the addition commutative law.

That is, 1 + 4 + 5 + 8 + 12 + ......33 + 36 + 37 + 40 = (1 + 40) + (4 + 37) + (5 + 36) + (8 + 33) Kehris + ......20+21）=41+41+41+……41。

In total, Wu Jing has 20 41.

So 20*41=820.

That is, the final answer is 820.

Typical difference series of arguments are noisy and sleepy.

Equal difference number series method empty thought: (first term + last term) * number of items 2 This problem is solved: (1+49)*25 2=625 Wanglou master! Give a little bit of loss, and make hard-earned money...
