Question 926911
<pre>
What do you want us to do with {sn}={n^2-n} ?????

{{{s[n]}}}{{{"=""}}}{{{n^2-n}}}

This??

{{{s[1]}}}{{{"=""}}}{{{1^2-1}}}{{{""=""}}}{{{1-1}}}{{{""=""}}}{{{"0"}}}

{{{s[2]}}}{{{"=""}}}{{{2^2-2}}}{{{""=""}}}{{{4-2}}}{{{""=""}}}{{{2}}}

{{{s[3]}}}{{{"=""}}}{{{3^2-3}}}{{{""=""}}}{{{9-3}}}{{{""=""}}}{{{6}}}

{{{s[4]}}}{{{"=""}}}{{{4^2-4}}}{{{""=""}}}{{{16-4}}}{{{""=""}}}{{{12}}}

{{{s[5]}}}{{{"=""}}}{{{5^2-5}}}{{{""=""}}}{{{25-5}}}{{{""=""}}}{{{20}}}

etc.

What do you want us to do for you?  You forgot to tell us.
We can't tell from just {sn}={n^2-n}.  There are no instructions 
given.  So what are we to do?  You can tell us in the thank-you
note and we'll get back to you.
