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 = 200

x + x + 2 + x + 4 + x + 6 + x + 8 = 200

해결 :

x = 36

x + 2 = 36 + 2 = 38

x + 4 = 36 + 4 = 40

x + 6 = 36 + 6 = 42

x + 8 = 36 + 8 = 44
