Question

Find the mean of first five natural numbers.

Answer 1

Find the mean of the first five natural numbers:

The first five natural numbers are $1,2,3,4$ and $5$.

$\mathrm{Mean}=\frac{\mathrm{Sum}\mathrm{of}\mathrm{terms}}{\mathrm{Number}\mathrm{of}\mathrm{terms}}$

$Mean=\frac{1+2+3+4+5}{5}$

$Mean=\frac{15}{5}$

$\therefore Mean=3$

Hence, the mean of the first five natural numbers is $3$.
