WebIt would be more than unconventional to use negative indices for these terms (e.g. a-5). 2) I've never seen the usage of negative indices or boundaries in any text book. Since the sigma notation is basically just a convention to write out long sums in a short way, it's probably best to stick to the prevailing convention of using non-negative ...

WebObserve that the numerators form the first four positive perfect squares (in order), and the denominators are 1 more than the corresponding numerators. So the nth term of the series is (n^2)/(n^2+1), for 1<=n<=4. So the sum of this four-term series can be written as sum n from 1 to 4 of (n^2)/(n^2+1).
