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.
