Can anyone help me out with this one?


I need to find an explicit formula for:

n 2
∑ i
i=1

I was already asked to find the explicit polynomial formula for the above equation which is

n·(n + 1)·(2·n + 1)

I'm not sure on what the difference is between the 2 formulas.

Thanks

Welcome to PF.

You are correction in your suspicion, the explicit polynomial formula is also the explicit formula.
