Solve the given number problem.

The sum of three consecutive even integers is –72. What is the least of these numbers?

A.
–26

B.
–22

C.
–30

D.
24

Answer 1

1. Let the first integer be n
then the second integer will be n+1
n+(n+1) = 107

Answer 2

2. Let the first integer be n
then the second odd integer will be n+2
n+(n+2) = 112

Answer 3

1. Let the first integer be n
the difference between three even integer is of 2
so second even integer is n+2
and third even integer is n+4
n+(n+2) + (n+4) = -72
