Chapter 6:
Sequence Application
The Sequence application provides you with the tools you need to
work with explicit sequences and recursive type sequences. Starting
up the Sequence application displays two windows.
1 Sequence Editor window
Use this window to input expressions for creating a sequence table.
2 Table window
Use this window to create and display table.
(a) Title: Shows the equation used in the calculations. The title is not
displayed when an item in column
n is selected.
(b) Column names
