Answer 2

Answer:

There are many solutions to this problem. If you include decimals and negative numbers there are an infinite number of answers.

To keep it simple though, the average of a set of numbers is the sum of the numbers divided by how many numbers there are. So if you want the average of 15 numbers to be 15, all you have to do is pick 15 numbers which add up to 225 (because 15 x 15 = 225).

A simple example - take the numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.

Add these up to get 105. To get the 15th number we need a total of 225, so the 15th number is 120.

Adding these up and dividing by 15 gives 15.
