1. To begin, add up all the numbers from the set for which you want to find the arithmetic mean. For example, you are given a sequence of five numbers: 8, 17, 22, 14 and 29. In this case, the first step in the calculation of the arithmetic mean is finding the sum of these numbers: 8 + 17 + 22 + 14 + 29 = 90.
2. Now, when the amount is found, divide it by the number of summed numbers. In our set had 5 numbers, so we divide 90 by 5. 90 : 5 = 18. The resulting number will be the average of the original set of numbers.
