Represent the numbers with

x

First number : x

Consecutive number 1 : x + 2

Consecutive number 2 : x + 4

Consecutive number 3 : x + 6

A.T.Q.:

x + x + 2 + x + 4 + x + 6 = 60

Решить

x + x + 2 + x + 4 + x + 6 = 60 : x = 12

x + 2 = 12 + 2 = 14

x + 4 = 12 + 4 = 16

x + 6 = 12 + 6 = 18

Select the largest solution:

18

The largest number : 18
