Question

The sum of three consecutive numbers is 87 What is the smallest of the three numbers?

Answer 1

28

Explanation:

The first step is to determine the three consecutive numbers.

`x+x+1+x+2 = 87`
`3x+3 = 87`
`3x+3-3 = 87-3`
`3x = 84`
`x = 28`
`x+1 = 29`
`x+2 = 30`

The three consecutive numbers are 28, 29, & 30,
28 is the smallest of the three.
