Represent the numbers with

x

First number : x

Consecutive number 1 : x + 2

Consecutive number 2 : x + 4

Consecutive number 3 : x + 6

A.T.Q.:

x + x + 2 + x + 4 + x + 6 = - 48

Решить

x + x + 2 + x + 4 + x + 6 = - 48 : x = - 15

x + 2 = - 15 + 2 = - 13

x + 4 = - 15 + 4 = - 11

x + 6 = - 15 + 6 = - 9

Select the smallest solution:

- 15

The smallest number : - 15
