What is the mean of first N odd numbers?
We know the first n odd terms are in arithmetic progression with common difference (d) = 2, i.e. the difference between any two consecutive numbers is two. Where a is the first term, n is the number of terms of the progression and d is the common difference. Hence, Mean of first n odd natural numbers is n.
