Sum of squares r

WebThe sum of squares for the first n integers = (n) (n+1) (2n+1)/6 - this is a pretty well known summation. To get the sum of squares of the first n EVEN integers, we just need to adjust that formula a little bit: plug in n/2 instead of n (so in this case 500 instead of 1000) and multiply the result by four.
