Question

продолжи ряды чисел:1)11,15,20,24,29,33, до 60; 2) 12,11,13,12,14,13,15,до 17.

Answer 1

1)11, 15, 20, 24, 29, 33, до 60;

закономерность: + 4, + 5

11 + 4 = 15...  15 + 5 = 20 ... 20 + 4 = 24... 24 + 5 = 29.. 29 + 4 = 33..

33 + 5 = 38... 38 + 4 = 42... 42 + 5 = 47... 47 + 4 = 51... 51 + 5 = 56...  ( 56 + 4 = 60... нужно ДО 60)

11, 15, 20, 24, 29, 33, 38, 42, 47, 51, 56.

2) 12,11,13,12,14,13,15,до 17

закономерность: - 1, + 2.

12 - 1 = 11... 11 + 2 = 13... 13 - 1 = 12... 12 + 2 = 14... 14 - 1 = 13 ... 13 + 2 = 15..

15 - 1 = 14... 14 + 2 = 16 ... 16 - 1 = 15  ( 15 + 2 = 17.. нужно ДО 17)

12, 11, 13, 12, 14, 13, 15, 14, 16, 15.
