Thank you for the opportunity to help you with your question!

The problem statement is: The average (A) of three numbers a,b, and c equals the sum of the three numbers divided by three.

Although there are different ways of calculating a mean (another word for average), the usual definition for average is exactly as stated: sum up the N values, then divide the total by N.

With N values, each number contributes (1/N)th of its value to the average of the N values. 

Hope this helps.
