Are you saying that you want to sum the values of (n^2)/10, say from n
= 1 to n = N (and you want a formula in terms of N)? If so, you can
use sum(n^2)/10 = (1/10)*sum(n^2), then find
sum(n^2: n=1..N) from any number of web pages, such as
http://www.math.utah.edu/~cherk/ccli/bob/sums.html
http://www.libraryofmath.com/summation-formulas.html
Do a Google search on "summation formulas" to find more.

I added a chart for visual aid. Can anyone tell me the sum
equation for the following set of data. The data goes beyond 5 I just wanted
to give a sense of where it is headed.

n (n^2)/10
1 .10
2 .40
3 .90
4 1.60
5 2.50

Thank you
