16-2 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.
c4 ( 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
0
/ b
0
( a
1
, b
1
.... Value of 1st term a
1
/ b
1
)
a
n
Str, b
n
Str ...... Pointer starting point for convergence/divergence graph
(WEB graph)
• The value of variable n 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.
