Key Concepts

Sequence

A sequence is an ordered list of numbers where each term is defined by a specific rule or formula. Understanding sequences involves knowing how to generate terms for given indices and examining their behavior as the index increases.

Alternating Sequence

An alternating sequence is characterized by terms that switch signs, often due to a factor like (-1)^n in the formula. This alternation can affect the pattern and properties of the sequence, especially in terms of convergence and oscillation.

Graphing Discrete Sequences

Graphing sequences involves plotting the individual terms as discrete points on a coordinate plane, with the index (n) on the horizontal axis and the corresponding term value on the vertical axis. This visual representation aids in recognizing patterns, trends, and overall behavior of the sequence.

Term Evaluation

Evaluating specific terms of a sequence by substituting different values of the index helps in understanding the sequence's structure and behavior. It provides concrete examples that can illustrate theoretical properties and support analysis, such as identifying possible growth trends or oscillatory behavior.
