The mean.

Explanation:

Prime number:

&

Mean: The mean is the average & when we add up all the numbers and then divide by the number of numbers.

Formula of the mean:

$m = \frac{x1 + x2 + x3 + .......... + xn}{n}$

Therefore,

$= > x = \frac{2 + 3 + 5 + 7 + 11 + 13 + 17 + 19}{8} \\ \\ = > x = \frac{77}{8} \\ \\ = > x = 9.6$
