솔루션 단계

Represent the numbers with

x

First number : x

Consecutive number 1 : x + 1

Consecutive number 2 : x + 2

Consecutive number 3 : x + 3

Consecutive number 4 : x + 4

A.T.Q.:

x + x + 1 + x + 2 + x + 3 + x + 4 = 200

x + x + 1 + x + 2 + x + 3 + x + 4 = 200

해결 :

x = 38

x + 1 = 38 + 1 = 39

x + 2 = 38 + 2 = 40

x + 3 = 38 + 3 = 41

x + 4 = 38 + 4 = 42

The numbers : 38, 39, 40, 41, 42
