Question

What is the sum of three consecutive whole numbers with 4y as the middle whole number?

Answer 1

Answer:  12y

=====================================================

Explanation:

4y is the middle value, or second value.

This means 4y-1 is the first value since it is immediately before 4y

Also, we know that 4y+1 is the value just after 4y

The order of the terms is: 4y-1, 4y, 4y+1

Add up those three expressions and simplify

(4y-1) + (4y) + (4y+1)

4y-1 + 4y + 4y+1

(4y+4y+4y) + (-1+1)

12y+0

12y

The three terms combine to 12y.
