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 w and then press 5 (RANG) to display the table range setting screen.
w5 (RANG)
1 ( a
0
) ........... Value for a
0
( b
0
)
2 ( a
1
) ........... Value for 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/divergence 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

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.
