Question from Marcelle, a parent:

The average of 5 even consecutive numbers is 112. What is the largest numbers?

Hi Marcelle,

Here is a hint.

Write down 5 consecutive even integers. It doesn't matter where you start maybe 78, 80, 82, ... Find the average of the consecutive even integers you wrote down. How does the average compare with the 5 integers you wrote down? Why is that?

Do it again with a different 5 consecutive even integers.

Write back if you need more assistance,
