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

Consecutive number 5 : x + 10

A.T.Q.:

x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 204

x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 204

해결 :

x = 29

x + 2 = 29 + 2 = 31

x + 4 = 29 + 4 = 33

x + 6 = 29 + 6 = 35

x + 8 = 29 + 8 = 37

x + 10 = 29 + 10 = 39
