Question

three consecutive integers add up to 51. What are these integers ?

Answer 1

Let the integers be a, a + 1 and a +2

According to question

a + a + 1 + a+ 2 = 51

=> 3a + 3 = 51

=> 3a = 48

=> a = 16

First integer = 16

Second integer = 17

Third integer = 18

Answer 2

Let the numbers be a , a+1, a+2
a+a+1+a+2=51
3a+3=51
a=51-3÷3
=48÷3
= 16
thus the numbers are 16,17&18
