Series
The math word "series" is referenced in the pages listed below.
The alternating series test is used to test for convergence when the terms of the underlying sequence alternate. Interactive calculus applet.
This page explores the power series, which is one where the terms of a sequence being summed are power functions. Interactive calculus applet.
A series is the sum of some set of terms of a sequence. For example, the sequence 2, 4, 6, 8, ... has partial sums of 2, 6, 12, 20, ... These partial sums are each a finite series. Interactive calculus applet.

... I have a small favor to ask. Over the years we have used advertising to support the site so it can remain free for everyone.
However, advertising revenue is falling and I have always hated the ads. So, would you go to Patreon and become a patron of the site?
When we reach the goal I will remove all advertising from the site.
It only takes a minute and any amount would be greatly appreciated.
Thank you for considering it! – John Page
