I realize that a variable can take any value, but some mathematical
functions limit the possible values. It's been a long time for me, but I
thought this particular function was stated as Sigma 1 to n = n*(n + 1)
/ 2 (where n 1). You don't really have a series if n is not 1.
Or it might

Oh, indeed!

It also works for n = 1, so n =
