Answer 2

See below:

Explanation:

The arithmetic mean is an average.

This means that you find the "central value in a set of numbers".

Say I scored `89, 90, 96, and 83` on some tests in school, and I wanted to calculate my average score.

I would add all of them together and divide by the number of scores that I was combining (which is `4`, because I took four tests):

`(89 + 90 + 96 + 83)/4 = "average"`

`358/4 = "average"`

`89.5 ="average"`

So `89.5` is my arithmetic mean score.
