How to Find the Average Between Three Numbers?

To find the average of three numbers, add the numbers together and then divide the sum by 3.

Here's a breakdown of the process:

1. Sum the Numbers: Add the three numbers together. For example, if your numbers are 5, 10, and 15, you would calculate 5 + 10 + 15 = 30.

2. Divide by Three: Divide the sum you calculated in step 1 by 3. In our example, you would calculate 30 / 3 = 10.

Therefore, the average of 5, 10, and 15 is 10.

Formula:

The formula for calculating the average of three numbers (a, b, and c) is:

Average = (a + b + c) / 3

Example:

Let's say you want to find the average of the numbers 7, 12, and 20.

1. Sum: 7 + 12 + 20 = 39
2. Divide: 39 / 3 = 13

Therefore, the average of 7, 12, and 20 is 13.

In summary, finding the average of three numbers is a straightforward process of addition and division.
