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
nmin has the same
value as tblStart .
4. Display the table
( ¥ ' ).
5. Scroll down the table
(D or 2 D) to see
more of the sequence.
Using a Sequence to Generate a Table
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.
Example: Fibonacci
Sequence
Fibonacci sequence
is in column 2.
You must enter {1,1}, although {1 1}
is shown in the sequence list.
