In this module sequences and series are investigated graphically, numerically and analytically. Visualization of sequences and series can be a powerful way to conceptualize convergence and the TI-89 Sequence Graphing mode can be used to assist in this visualization.

21.1 - Sequences

21.2 - Series and Sequences of Partial Sums

21.3 - Recursively Defined Sequences

After completing this module, you should be able to do the following:

• Use the sequence and summation features of the TI-89
• Graph sequences with your TI-89
• Use the TI-89 to make tables of sequences
• Graph the sequence of partial sums for a series
• Use graphs and tables to support the concept of convergence
• Define sequences recursively
