Formula To Find Sum Of A Series Of Numbers – Examples Included

If you have an average of a series of numbers, how can you find their sum?

Use the formula:Sum = Average x Number of termsIf the average of 10 numbers is 50, then they add up to 10 x 50, or 500.

To find the sum of a series of numbers, you can use the following formula:

Sum = Average x Number of Terms

Let’s say you have a series of 5 numbers: 10, 20, 30, 40, and 50. To find their sum, you need to first calculate the average of these numbers:

Average = (10 + 20 + 30 + 40 + 50) / 5
Average = 30

Now that you have the average, you can find the sum by multiplying the average by the number of terms:

Sum = Average x Number of Terms
Sum = 30 x 5
Sum = 150

So the sum of the series of numbers 10, 20, 30, 40, and 50 is 150.
