Question

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

Answer 1

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

The first 10 even natural numbers are $2,4,6,8,10,12,14,16,18$ and $20$.

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

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

$Mean=\frac{110}{10}$

$\therefore Mean=11$

Hence, the mean of first $10$ even natural numbers is $11$.
