How do I solve these two summation problems?
I need to know how to get the results of:
1*3 + 2*4 + 3*5 + .... + n*(n+2) = ?
and
1*3 + 3*5 + 5*7 + .... + (2n-1)*(2n+1) = ?
Please help if you can.
Thank you.
Using well-known sums such as the sum of the first n integers and the sum of first n integers squared, we find two product sums
