The Fibonacci Sequence
Summary
• In this tutorial, you’ll be generating the Fibonacci Sequence. The steps in the tutorial include:– Creating a Spreadsheet Window.– Generating the first 20 terms of the Fibonacci
Sequence.– Creating a Statistics Window.– Graphing the Fibonacci Sequence.
Create a Spreadsheet Window
Click on the + tool to activate this menu.
Add Column Headings
Move to the top of Column A and add this column heading. Press Enter.
Add Column Headings
Move to the top of Column B and add this column heading.
Generate a Sequence for Column A
Highlight the Formula Cell for Column A. Then press Menu and select Data > Generate
Sequence.
Generate a Sequence for Column A
You’ll be generating a sequence of numbers from 1 to 20. Configure the Sequence as shown here.
Generate a Sequence for Column A
You’ll see the numbers 1-20 in Column A.
Generate the Fibonacci Sequence
Now generate the Fibonacci Sequence in the Formula Cell for Column B. Press Menu and Generate Sequence.
Generate the Fibonacci Sequence
Configure the Sequence as shown in the highlighted cells. The press OK.
Generate the Fibonacci Sequence
You’ll now see the first twenty terms of the Fibonacci Sequence in Column B.
Graph the Fibonacci Sequence
Create a Data & Statistics Window by clicking on the + sign on the upper-left part of the screen.
Graph the Fibonacci Sequence
We need to assign the values in Column A to the horizontal axis and the values in Column B to the vertical axis.
Graph the Fibonacci Sequence
Tap on the horizontal axis and select “term”.
Graph the Fibonacci Sequence
Click on the vertical axis and select “FibonacciSequence”.
