Question

Find the mean of first six odd natural numbers.

Answer 1

First six odd natural numbers are 1, 3, 5, 7, 9 and 11.

Mean of the first six natural numbers = $\frac{\mathrm{Sum}\mathrm{of}\mathrm{the}\mathrm{given}\mathrm{observations}}{\mathrm{Number}\mathrm{of}\mathrm{the}\mathrm{given}\mathrm{observations}}$

= $\frac{1+3+5+7+9+11}{6}=\frac{36}{6}=6$

Mean of the first six odd natural numbers is 6.
