5-9 Graphing a Recursion Formula
k k k k 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.
