Why do you suppose there were seemingly random questions about the average of two numbers?

Because finding the missing number in an average of two numbers, when given the average is exactly like finding the an endpoint when given a midpoint.

Because I am random.

Because when given two numbers, you can find their average by using the Midpoint Formula.
