解答ステップ

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 = - 44

解く

x + x + 2 + x + 4 + x + 6 = - 44 : x = - 14

x + 2 = - 14 + 2 = - 12

x + 4 = - 14 + 4 = - 10

x + 6 = - 14 + 6 = - 8

The numbers : - 14, - 12, - 10, - 8
