To find the average for a set of numbers we use the following formula:


\text{Average}=\frac{\text{SUM}}{AMOUNT\text{ OF NUMBERS}}

That means the average will be the result of the division between the sum of the scores by the amount of scores we have.

The sum of the scores is:


24+27+22+30+18=121

Sum: 121

And the amount of numbers is the number of scores we have, in this case, we have 5 scores.

Amount of numbers: 5

So the average will be:


\text{Average}=(121)/(5)

which is equal to:


\text{Average=24.2}

Answer: 24.2
