Using A Sequence To Generate A Table - Texas Instruments TI-89 Manual Book

Using a Sequence to Generate a Table

Example: Fibonacci
Sequence
Previous sections described how to graph a sequence. You
can also use a sequence to generate a table. Refer to
Chapter 13 for detailed information about tables.
In a Fibonacci sequence, the first two terms are 1 and 1. Each
succeeding term is the sum of the two immediately preceding terms.
1. On the Y= Editor
( ¥ # ), define the
sequence and set the
initial values as shown.
2. Set table parameters
( ¥ & ) to:
tblStart = 1
@tbl = 1
Independent = AUTO
3. Set Window variables
( ¥ $ ) so that
has the same
nmin
value as .
tblStart
4. Display the table
( ¥ ' ).
5. Scroll down the table
(D or 2 D) to see
more of the sequence.
You must enter {1,1}, although {1 1}
is shown in the sequence list.
This item is dimmed if you are not
using TIME axes.
Fibonacci sequence
is in column 2.
