Question

Find the mean of the first five whole numbers.

Answer 1

First $5$ whole numbers are $0,1,2,3,4$

$\Rightarrow$ Sum of 5 whole numbers, S $=0+1+2+3+4=10$

$\Rightarrow$ Number of whole numbers $\left(n\right)=5$

$\Rightarrow$ $\text{Mean}\left(\overline{x}\right)=\frac{\text{sum of whole numbers (S)}}{\text{no. of whole numbers (n)}}=\frac{10}{5}=2$
