Question

Find the mean of the first ten odd natural numbers?

Answer 1

Compute the required mean:

The numbers which only contain positive integers, i.e. $1,2,3,4,5,6.......$ with zero, fractions, decimals and negative numbers excluded are known as natural numbers.

The first ten odd natural numbers are:

$1,3,5,7,9,11,13,15,17,19$

We know that the formula of the mean can be given as:

$\text{Mean=}\frac{\text{Sum of all the abservations}}{\text{Total number of observations}}$

Mean calculation:

$Mean=\frac{1+3+5+7+9+11+13+15+17+19}{10}=\frac{100}{10}=10$

Hence, the mean is $10$.
