Question

найди закономерность в рядах и запиши в каждый по 4 числа 1.298 287 265 232 188 ....2. 1280 640 320 160 80.... 3.2 3 5 8 13 21 ....

Answer 1

1. 298,287,265,232,188,133,67,-10,-98 (может быть, последние два числа тебе не надо писать)

закономерность: из первого числа вычли 11(298-11=287), из второго 22(287-22=265), из третьего 33, из четвертого 44 ит.д

2. 1280,640,320,160,80,40,20,10,5
закономерность: первое число поделили на 2(1280: 2=640, второе тоже делим на 2 и.т.д

3. 2,3,5,8,12,21,34,55,89,144
закономерность: рядом стоящие два числа складываются, образуя третье: 2+3=5,3+5=8 и.тд.
 

Answer 2

Finding the Pattern in the Given Number Series

Let's analyze each number series and identify the pattern in each one.

1. 1. 298, 287, 265, 232, 188, ... 2. 2. 1280, 640, 320, 160, 80, ... 3. 3. 2, 3, 5, 8, 13, 21, ...

Pattern in the First Number Series

The pattern in the first number series seems to involve a decreasing sequence. Let's calculate the differences between consecutive numbers to identify the pattern.

298 - 287 = 11 287 - 265 = 22 265 - 232 = 33 232 - 188 = 44

It appears that the differences between consecutive numbers are increasing by 11 each time. This suggests that the next difference would be 55. Let's verify this pattern by checking the next number in the series.

188 - 55 = 133

So, the next number in the series would be 133.

Pattern in the Second Number Series

The pattern in the second number series also seems to involve a decreasing sequence. Let's calculate the differences between consecutive numbers to identify the pattern.

1280 / 2 = 640 640 / 2 = 320 320 / 2 = 160 160 / 2 = 80

It appears that each number is being divided by 2 to obtain the next number in the series.

Pattern in the Third Number Series

The pattern in the third number series seems to involve an increasing sequence. Let's calculate the differences between consecutive numbers to identify the pattern.

3 - 2 = 1 5 - 3 = 2 8 - 5 = 3 13 - 8 = 5 21 - 13 = 8

It appears that the differences between consecutive numbers are following a Fibonacci sequence, where each number is the sum of the two preceding ones.

Conclusion

1. The next number in the first series is 133. 2. The next number in the second series is 40 (80 / 2). 3. The next number in the third series is 34 (21 + 13).
