The remainder obtained by dividing the first term by the second term is the third term, and the remainder obtained by dividing the second term by the third term is equal to the fourth term, and so on. 1 1 divided by 5, the remainder is 1, followed by 157, 65, 27, 1 1, 5 and below.

Second,

You can regard the number of the first term as 1+0, then the numerator of the second term is the sum of the numerator and denominator of the first term, and the numerator of the third term is the sum of the numerator and denominator of the second term, so that the law between molecules can be found, and the numerator of the fifth term is 34. Look at the denominator again. The denominator of the second term is equal to the sum of the denominator of the first term and the numerator of the second term, and the denominator of the third term is equal to the sum of the denominator of the second term and the numerator of the third term. Then we can get that the denominator of the fifth item is equal to the sum of the denominator of the fourth item and the numerator of the fifth item, which is 55. So the answer is 34/55.

Third,

67-54= 13

54-46=8

46-35= 1 1

35-29=6

So you can see that after subtraction, one becomes an odd number column and the other becomes an even number column, so the number obtained by the next subtraction should be 9, and 29 minus 20 equals 9, so the answer is 20.

Fourth,

_, I've been thinking about it all morning, but I still have no idea! ! I want to confirm whether there is any problem with the topic, or give the option of the fourth topic, because some topics of civil servants can't be done without options!

The fourth question can be answered according to the stem:

14=6*2+2

20=6*4-4

54=6*8+6

76=6* 14-8

First, it's six times ... followed by one plus one minus, and the numbers 2, 4, 6 and 8 become arithmetic progression. This rule is easy to see. 2, 4, 8 and 14, this series is a two-level arithmetic progression, that is, the former item is subtracted from the latter item to get a new series of 2, 4, 6, which is also arithmetic progression.

But according to this rule, the next number should be 6*22+ 10= 142.

You didn't give an answer.

Are you satisfied with the first three courses? !
