Краткое пояснение: Продолжим ряды чисел, соблюдая закономерности в каждом столбце.
Пошаговое решение:
-
Первый столбик:
- 19 + 19 ⋅ 0 = 19 + 0 = 19
- 18 + 18 ⋅ 1 = 18 + 18 = 36
- 17 + 17 ⋅ 2 = 17 + 34 = 51
- 16 + 16 ⋅ 3 = 16 + 48 = 64
- 15 + 15 ⋅ 4 = 15 + 60 = 75
-
Второй столбик:
- 11 − 22 : 2 = 11 − 11 = 0
- 22 − 33 : 3 = 22 − 11 = 11
- 33 − 44 : 4 = 33 − 11 = 22
- 44 − 55 : 5 = 44 − 11 = 33
- 55 − 66 : 6 = 55 − 11 = 44
-
Третий столбик:
- (4 + 26) : 10 ⋅ 9 = 30 : 10 ⋅ 9 = 3 ⋅ 9 = 27
- (5 + 25) : 10 ⋅ 8 = 30 : 10 ⋅ 8 = 3 ⋅ 8 = 24
- (6 + 24) : 10 ⋅ 7 = 30 : 10 ⋅ 7 = 3 ⋅ 7 = 21
- (7 + 23) : 10 ⋅ 6 = 30 : 10 ⋅ 6 = 3 ⋅ 6 = 18
- (8 + 22) : 10 ⋅ 5 = 30 : 10 ⋅ 5 = 3 ⋅ 5 = 15
