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 = - 470

解く

x + x + 1 + x + 2 + x + 3 + x + 4 = - 470 : x = - 96

x + 1 = - 96 + 1 = - 95

x + 2 = - 96 + 2 = - 94

x + 3 = - 96 + 3 = - 93

x + 4 = - 96 + 4 = - 92

Select the smallest solution:

- 96

The smallest number : - 96
