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 = 145

x + x + 1 + x + 2 + x + 3 + x + 4 = 145

حلّ:

x = 27

x + 1 = 27 + 1 = 28

x + 2 = 27 + 2 = 29

x + 3 = 27 + 3 = 30

x + 4 = 27 + 4 = 31
