OK,average is the usual way of finding the average of a set of numbers is to add all the numbers in the set and divide the sum by how many numbers there are in a set.If there are 5 numbers in all,then add the 5 numbers and divide the sum by 5.

To find the average of a group of numbers, first you must know:
- The sum of all the numbers presented
- How many numbers are presented

In general knowledge, there are two steps.
First, you find the sum of the numbers presented.
Second, divide that sum by how many numbers are found in that group.

Let's have some examples!

Find the average of:

50, 100, 150, 200

Find the sum of those numbers:
200
150
100
  50
___
500

Next, divide the sum by how many numbers are found. Therefore:
500÷4

500/4=125.

Final Answer:
The average is 125.

Let's have a quiz:

1.) Find the average of 125, 250, and 500.

2.) Find the average of 10, 20, and 30.

3. Find the average of 150, 260, and 60.
