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 = 135

解く

x + x + 2 + x + 4 + x + 6 + x + 8 = 135 : x = 23

x + 2 = 23 + 2 = 25

x + 4 = 23 + 4 = 27

x + 6 = 23 + 6 = 29

x + 8 = 23 + 8 = 31
