IM Alg2.1.5 Practice: Sequences as Functions

This example demonstrates how sequences can be viewed as functions defined on positive integers, showing the correspondence between term indices and values through graphical and algebraic representations. Core mathematical concepts include the definition of sequences, function notation, recursive and explicit formulas, and the discrete point-plot nature of sequence graphs. Construction notes: the summary lists objects a through i, likely involving GeoGebra commands such as Sequence or list generation to create discrete points, and using coordinate axes to display how sequence terms change with index. Suitable for high school algebra practice on sequences and functions, helping students understand that sequences are a special type of function and how to analyze patterns using graphs and tables.
