What is the average of all the natural numbers from 1 to 87?

Correct option is D

Given: 

Numbers from 1 to 87

Formula used: 

$$Average = \frac{First \ number + Last \ number}{2}$$ 

Solution: 

First term is 1 and last term is 87 

$$Average = \frac{1 + 87}{2} = \frac{88}{2} = 44$$ 

Thus, the average of all natural numbers from 1 to 87 is 44
