Question

Find The Average Of First Ten Prime Numbers?

Answer 1

Finding the Average Of First Ten Prime Numbers:

A prime number is a whole number greater than 1 whose only factors are 1 and itself.

Therefore the first ten prime numbers are $2,3,5,7,11,13,17,19,23,29$

We know that

$Average=\frac{Sumofthenumbers}{Numberofnumbers}$

$$\begin{gathered} \therefore Average=\frac{(2+3+5+7+11+13+17+19+23+29)}{10} \\ =\frac{129}{10} \\ =12.9 \end{gathered}$$

Hence, the Average of first $10$ prime number is $12.9$.
