## Solution 34672: Graphing the Fibonacci Sequence Using the TI-84 Plus C Silver Edition Graphing Calculator.

### How can I graph the Fibonacci sequence using the TI-84 Plus C Silver Edition graphing calculator?

In a Fibonacci sequence the first two terms are 1 and 1. Each succeeding term is the sum of the two immediately preceding terms. Follow the procedure below to graph the Fibonacci sequence:

• Press [MODE].
• Arrow down to Func.
• Arrow over to SEQ and press [ENTER]. • Press [Y=].
• For nMin=, input .
• For u(n)=, input [2ND] [u] [(] [X,T,
q,n] [-]  [)] [+] [2ND] [u] [(] [X,T,q,n] [-]  [)].
• For u(nMin)=, input [2ND] [{]  [,]  [}]. • Press [GRAPH].
• To adjust the window, press [ZOOM] and press 6: ZStandard. • Press [2ND] [TBLSET] to setup the table options.
• Input 1 for TblStart= and 1 for Tbl=.
• Press [2ND] [QUIT].
• Press [2ND] [TABLE] to see the table of n and u(n). Please see the TI-83 Plus family and TI-84 Plus C Silver Edition guidebook for additional information.
