The numbers : 58, 60, 62, 64, 66

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

Consecutive number 4 : x + 8

A.T.Q.:

x + x + 2 + x + 4 + x + 6 + x + 8 = 310

解く

x + x + 2 + x + 4 + x + 6 + x + 8 = 310 : x = 58

x + 2 = 58 + 2 = 60

x + 4 = 58 + 4 = 62

x + 6 = 58 + 6 = 64

x + 8 = 58 + 8 = 66

The numbers : 58, 60, 62, 64, 66
