Partial Sum Calculator Program Software Series As LimitAnd they say write a rule for what the actual Nth term is going to be. Now to help us with this, let me just create a little visualization here. That is s sub n. This whole thing is s, let me this whole thing is sub n, which is equal to n plus one, over n plus 10. Now if I wanna figure out a sub n, which is the goal of this exercise, well I could subtract out the sum of the first n minus one terms. So I could subtract out this. So that is s, that is s sub n minus one, and what would that be equal to. So itd be n minus one plus one over n minus one plus 10, which is equal to n over n plus nine. But we could combine these terms, add these two fractions together. And this is actually going to be the case for n greater than one. We can add these two fractions by having a common denominator. So we have n times n plus 10, over n plus nine times n plus 10. So this is n squared plus 10 n and remember were gonna subtract this. So there you have it, weve expressed, weve written a rule for a.
