What do you want us to do with {sn}={n^2-n} ?????

s%5Bn%5D%22=%22%22n%5E2-n

This??

s%5B1%5D%22=%22%221%5E2-1%22%22=%22%221-1%22%22=%22%22%220%22

s%5B2%5D%22=%22%222%5E2-2%22%22=%22%224-2%22%22=%22%222

s%5B3%5D%22=%22%223%5E2-3%22%22=%22%229-3%22%22=%22%226

s%5B4%5D%22=%22%224%5E2-4%22%22=%22%2216-4%22%22=%22%2212

s%5B5%5D%22=%22%225%5E2-5%22%22=%22%2225-5%22%22=%22%2220

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.
