WebFirst the series is 2n+1. We want to prove that n^2 = S_n, so plugging in n we see that n^2=n^2, therefore the next partial sum is the next term (2n+1) + the sum of the pervious n terms (n^2). Plugging in the next n into our partial sum formula we see that (n+1)^2 = n^+2n+1, which is what we got earlier. WebSum of Squares of The First n Natural Numbers.

The sum of the first two terms is $3\cdot 2+2\cdot2^2=14$, so the second term is $14-5=9$. The sum of the first three terms is $3\cdot 3+2\cdot3^2=27$ so the third term is $27-14=13$. The terms run $5,9,13\dots$ so the common difference is $4$.
