Inputting a Recursion Formula and
Generating a Table
Example 1
To input
a
n
+1
= 2
a
n
+ 1 and generate a table of values as the
value of
n
change from 1 to 6
Make
a
1
= 1.
1. Specify the recursion formula type as linear recursion between two terms and
then input the formula.
c
4
(
n
,
a
n
···)
2
(
a
n
)
+b
2. Press
w5
(RANG) to display the table range setting screen, which contains
the following items.
• {
a
0
}
/
{
a
1
} ... setting of value for {
a
0
(
b
0
)}/{
a
1
(
b
1
)}
The table range settings specify the conditions that control the value of variable
n
in the recursion formula, and the initial term of the numeric value table. You should
also specify a starting point for the pointer when drawing a convergence/diver-
gence graph (WEB graph) for a formula for linear recursion between two terms.
Start ................ Starting value of variable
n
End ................. Ending value of variable
n
a
0
,
b
0
............... Value of 0th term
a

/
b

(
a

,
b

.... Value of 1st term
a

increments by 1.
3. Specify the range of the table.

4. Display the table of the recursion formula. At this time, a menu of table
functions appears at the bottom of the screen.
