We need to find the average of the first 121 odd natural numbers.
Formula used:
The average of the first n odd natural numbers is equal to the middle number in the sequence.

The sequence of the first 121 odd natural numbers is: 1, 3, 5, ..., 241.
The middle number in the sequence is determined by the formula:
⇒ Middle number = (nth odd number) = 2 × n - 1
