The average of the first ten natural numbers is 

To find out the average we need to calculate the mean value of the first ten natural numbers. The first 10 natural numbers are$1,2,3,4,5,6,7,8,9 and 10$.

Mean = $\frac{(sum of all the observations)}{(total number of observations)}$

Therefore, the mean will be $\frac{\text{1+2+3+4+5+6+7+8+9+10 }}{10}=\frac{55}{10}=\frac{11}{2}$
