[tex]\frac{1}{n^{2}}+\frac{1}{\left(n-1\right)^{2}}+\frac{1}{\left(n-2\right)^{2}}+...+1[/tex]

Can I manipulate this into some form that would make it easier to put in Excel? I'm pretty stuck and any suggestions would be much appreciated!

Thanks,

Kerry

[EDIT] Just wanted to make it clearer - My goal is to have some formula in one cell that references just one other cell to get the result.
