the sum of three consecutive integers is 132. what are the three integers?

Question

can somebody help me understand how to do problems like these?

Answer 1

Hi

Let the three integers be

a, a+1 and a+2

Sum of three = 132

a+a+1 +a+2 = 132

so 3a + 3 = 132

3a = 132-3

3a= 129

a= 129/3 = 43

So integers are 43, 44 and 45
