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 {an}, composed of an, n
• Linear two-term recursion composed of an+1, an, n
• Linear three-term recursion composed of an+2, an+1, an, n
Set Up
1. From the Main Menu, enter the RECUR mode.
Execution
2. Specify the recursion type.
3(TYPE)1(an) ... {general term of sequence an}
2(an+1) ... {linear two-term recursion}
3(an+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.
