Question

Mean of first n even prime numbers

Answer 1

Answer:

The average of first n natural numbers = (n+1)/2. The average of squares of first n natural numbers = (n+1)(2n+1)/6. ... The average of odd numbers from 1 to n = (last odd number+1)/2. The average of even numbers from 1 to n = (last even number+2)/2. The average of squares of first n odd numbers = (2n+1)(2n-1)/3.
