Question

Find the mean of the first$10$ even natural numbers.

Answer 1

Solve for the mean of the first ten even natural numbers.

The first $10$ even natural numbers are given below:

$2,4,6,8,10,12,14,16,18,20$

Mean = Sum of all the observations $/$ The total number of observations.

Mean = $\frac{(2+4+6+8+10+12+14+16+18+20)}{10}$

$\Rightarrow \frac{110}{10}$

$\Rightarrow 11$

Hence, the mean of the first ten even natural numbers is $11.$
