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

A.T.Q.:

x + x + 1 + x + 2 + x + 3 = - 186

x + x + 1 + x + 2 + x + 3 = - 186

해결 :

x = - 48

x + 1 = - 48 + 1 = - 47

x + 2 = - 48 + 2 = - 46

x + 3 = - 48 + 3 = - 45

Select the largest solution:

- 45

The largest number : - 45
