26 мая 2021 г. · On the other hand, a partial sums sequence is called s n s_n s​n​​, and its n n n values increase by additive increments.

A Partial Sum is the sum of part of the sequence. The sum of infinite terms is an Infinite Series. And Partial Sums are sometimes called "Finite Series".

25 янв. 2013 г. · To get an from Sn, use an=Sn−Sn−1. In your case, assuming Sn=8−4n: an=4n−1−4n=4n(n−1). EDIT. When Sn=8−n4n: an=n−14n−1−n4n=4n−44n−n4n=3n−44n. general formula for partial sum of series - Math Stack Exchange Given the partial sum of a series, how do I find an?
