Average of Integers in a Sequence Calculator

Welcome to the Average of Integers in a Sequence Calculator. To calculate the average of any set of numbers in a sequence, you divide the sum of the numbers by the total numbers in the set (Sum/Total).

To calculate the sum of all the integers (whole numbers) in a sequence, you use the formula below where a is the low number and b is the high number:

Sum = ((b - a + 1) ÷ 2) × (a + b)

To calculate the total number of integers in a sequence, we calculate the different between the low and high number and then add 1. See formula below. Once again, a is the low number and b is the high number:

Total = b - a + 1

Finally, as mentioned above, you can now calculate the Average by dividing the Sum by the Total:

Average = Sum ÷ Total

No need to get out your calculator and follow the steps above. Instead, please enter the low and high numbers of your sequence below, so we can calculate the average for you.
