解答ステップ

Represent the numbers with

x

First number : x

Consecutive number 1 : x + 1

Consecutive number 2 : x + 2

Consecutive number 3 : x + 3

A.T.Q.:

x + x + 1 + x + 2 + x + 3 = - 14

解く

x + x + 1 + x + 2 + x + 3 = - 14 : x = - 5

x + 1 = - 5 + 1 = - 4

x + 2 = - 5 + 2 = - 3

x + 3 = - 5 + 3 = - 2

The numbers : - 5, - 4, - 3, - 2
