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.)

What is the nth term of 8 13 18 23 28?
t{n} = (3n⁵ - 45n⁴ + 255n³ - 675n² + 1022n - 240)/40 This gives t{1..5} = {8, 13, 18, 23, 28} and continues t{6...} = {42, 92, 232, 552, 1187, ...} However, your teacher probably wants the much simpler: t{n} = 5n + 3 Which also gives t{1..5} = {8, 13, 18, 23, 28} but continues t{6...} = {33, 38, 43, 48, ...} There are infinitely many formulae that can be given to give the terms t{1..5} = {8, 13, 18, 23, 28}; they all differ in what terms follow. Which means that any formula for the nth term of t{1..5} = {8, 13, 18, 23, 28} is ONLY valid for n = 1, 2, ..., 5 as 5 terms have been given.
