5-9 Graphing a Recursion Formula
k Generating a Number Table from a Recursion Formula
Description
You can input up to three of the following types of recursion formulas and generate a number
table.
• General term of sequence {
a n }, composed of a n , n
• Linear two-term recursion composed of
a n +1 , a n , n
• Linear three-term recursion composed of
a n +2 , a n +1 , a n , n
Set Up
1. From the Main Menu, enter the RECUR mode.
Execution
2. Specify the recursion type.
3 (TYPE)1 (
a n ) ... {general term of sequence a n }
2 (
a n +1 ) ... {linear two-term recursion}
3 (
a n +2 ) ... {linear three-term recursion}
3. Input the recursion formula.
4. Specify the table range. Specify a start point and end point for
n . If necessary, specify a
value for the initial term, and a pointer start point value if you plan to graph the formula.
5. Display the recursion formula number table.
