- 18.1 Sequences: What is a sequence?a list of numbers written in a specific order
Represented by "asubn", it could be a function.
Those functions generate terms - 28.1 Sequences: What is a sequence? asubn from n=0 to ∞{a₀, a₁, a₂,…, asubn, asubn+1,…}
- 38.1 Sequences: How to graph the sequence of asubnplot the points (n, asubn)) as n ranges over all possible values on a graph

- 48.1 Sequences: that begin with positive termscontains a function with
(-1)ⁿ⁺¹ - 58.1 Sequences: that begin with negative termscontains a function with
(-1)ⁿ - 68.1 Sequences: for "∑" if "n" is not specified...use n=1
