Correct option is A

Given:

First 120 odd natural numbers

Formula Used:

The $$n^\text{th}$$​ odd number = 2n - 1

Average of first nn odd numbers = $$\frac{\text{1st} + \text{nth}}{2}$$

$$= \frac{1 + (2n - 1)}{2} = n$$​​​

Solution:

For n = 120,

Average = 120

Thus, The average of first 120 odd natural numbers is 120.
