What is the mean of first n odd natural numbers?

Options

  1. An
  2. B(n+1) / 2
  3. Cn(n+1) / 2
  4. Dn+1

Correct answer

A. n

Step-by-step solution

Sum of first n odd natural numbers aligned & S =1+3+5+ +(2 n-1) & S = n 2 (1+2 n-1)=n^2 aligned mean = sum of observations number of observations = n^2 n =n
