We also show a proof using Algebra below. We often use Sigma Notation for infinite series. Our example from above looks like:. Let's add the terms one at a time.

## Alternating Series - Mathematics LibreTexts

So far in this chapter, we have primarily discussed series with positive terms. In this section we introduce alternating series—those series whose terms alternate in sign. We will show in a later chapter that these series often arise when studying power series. After defining alternating series, we introduce the alternating series test to determine whether such a series converges. A series whose terms alternate between positive and negative values is an alternating series. For example, the series. Any series whose terms alternate between positive and negative values is called an alternating series.

### Alternating series

What is an example of a convergent alternating series where the conditions of the alternating series test do not hold? First Name. Your Response. By recognizing each series below as a Taylor series evaluated at a particular value of x, find the sum of each convergent series. Which one of the following statements is true about the series the series from n equals 1 to infinity of the quotient of negative 1 raised to the nth power and n?

In mathematics , an alternating series is an infinite series of the form. The signs of the general terms alternate between positive and negative. Like any series, an alternating series converges if and only if the associated sequence of partial sums converges.
