(D) The sum of the first $n$ odd natural numbers is given by the formula $S_n = n^2$.The arithmetic mean of a set of numbers is defined as the sum of the numbers divided by the count of the numbers.For the first $n$ odd natural numbers,the arithmetic mean is $\frac{S_n}{n} = \frac{n^2}{n} = n$.Given $n = 20$,the arithmetic mean is $20$.
