Here's how to find it:

  1. Add all the numbers together.
  2. Divide the sum by the total number of values in the set.

For example, if you have the numbers 2, 3, 5, and 7, you would:

  1. Add them together: 2 + 3 + 5 + 7 = 17
  2. Divide the sum by the number of numbers (4): 17 / 4 = 4.25

So, the average of 2, 3, 5, and 7 is 4.25.

This method works for any set of numbers, whether they are whole numbers, decimals, or even negative numbers.

Here are some additional things to keep in mind:

  • There are other types of averages besides the mean, such as the median (the middle number) and the mode (the most frequent number).
  • If you're working with a large set of numbers, you can use a calculator or spreadsheet software to find the average.
