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

Consecutive number 5 : x + 5

A.T.Q.:

x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 = 387

x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 = 387

해결 :

x = 62

x + 1 = 62 + 1 = 63

x + 2 = 62 + 2 = 64

x + 3 = 62 + 3 = 65

x + 4 = 62 + 4 = 66

x + 5 = 62 + 5 = 67
