Use the definition of "average", as follows.Add all the numbers up. Call the result "sum". Then count how many numbers there are, and divide "sum" by that number.
In this particular case, the interval between any two consecutive numbers is the same (an arithmetic sequence); in this case, you can use the following shortcut: the average is simply the number in the middle. (And if there are an even number of numbers, take the average between the two numbers in the middle.)
