Question

The sum of three consecutive numbers is 45. What are the three numbers? Write an equation and solve

Answer 1

Call n the first integer so you get:

`n + ( n + 1 ) + ( n + 2 ) = 45`

`3 n + 3 = 45`

`3 n = 42`

`n = 14`

The integers are: 14 , 15 , 16

Answer 2

14 + 15 + 16 = 45 . Let the three consecutive integers be x, x+1 and x+2. Therefore the numbers would be 14, 15 & 16. answer: 14, 15 and 16.
