4. Display the table of the recursion formula. At this time, a menu of table functions
appears at the bottom of the screen.
J6 (TABL)
Value in currently highlighted cell
• Displayed cell values show positive integers up to six digits, and negative inte-
gers up to five digits (one digit used for negative sign). Exponential display can
use up to three significant digits.
• You can see the entire value assigned to a cell by using the cursor keys to move
the highlighting to the cell whose value you want to view.
• You can also display the sums of the terms
(
Σ
a
n
or
Σ
b
n
) by turning on
Σ
Display.
Example 2 To input a
n +2
= a
n +1
+ a
n
(Fibonacci series) and generate a table
of values as the value of n change from 1 to 6
Make a
1
= 1 and a
2
= 1.
1. Specify the recursion formula type as linear recursion between three terms and
then input the formula.
3 (TYPE) 3 ( a
n +2
)
4 ( n , a
n
...)
3 ( a
n +1
) +2 ( a
n
)
2. Press w and then press 5 (RANG) to display the table range setting screen.
