Answer 2

The average of 101 natural numbers is 51

Step-by-step explanation:

To find: The average of first 101 natural number

As we know

The sum of n natural numbers is given by

$Sum = \dfrac{n(n+1)}{2}$

where n is the numbers of terms of natural number

n= 101

Therefore we have

$sum= \dfrac{101\times (101+1)}{2} = \dfrac{101 \times 102}{2} = 101 \times 51$

Now as we know

$Average = \dfrac{\text {Sum of observation}}{\text {Number of observation} }= \dfrac{101\times 51}{101} =51$

Hence, the average of 101 natural numbers is 51
