In the latter part of a calculus course, one begins to work with sequences and series. A sequence is simply a function whose domain is limited to integers rather than real numbers. We illustrate with the sequence .
To work with sequences, first we need to set the function mode to sequence. Press to access the mode menu. In the fourth line of the mode menu (the Func line), highlight Seq and then press . We also recommend setting the graph style to Dot (highlight Dot and press ).
One may work with sequences now just like with functions. You may obtain a sequential value or a table of values. For example, press to return to the home screen. Press TBLSET to access the table setup screen. Set up the table as indicated in the screen below at left. To view the table, press . For example, note that u5 .038436
