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”.
