4. Sequence Characteristics
Convergence/Divergence: As we look at more and more terms in the sequence, do those terms have a limit?
Increasing/Decreasing: Are the terms of the sequence growing larger, growing smaller, or neither? A sequence that is strictly increasing or strictly decreasing is called a monotonic sequence.
Boundedness: Are there values we can stipulate that describe the upper or lower limits of the sequence?

5. What is an Infinite Series?
We start with a sequence {an}, n going from 1 to ∞, and define {si} as shown.
The {si} are called partial sums. These partial sums themselves form a sequence.
An infinite series is the summation of the infinite number of terms in the sequence {an}.

6. What is an Infinite Series?
Our goal is to determine whether an infinite series converges or diverges. It must do one or the other.
If the sequence of partial sums {si} has a finite limit as n −−> ∞, we say that the infinite series converges. Otherwise, it diverges.
