1. TI-Nspire App Tutorial
Geometric Sequences

2. Summary
• In this tutorial, you’ll be generating the
Geometric Sequences. The steps in the
tutorial include:
– Creating a Spreadsheet Window.
– Generating a 10-term increasing Geometric Series.
– Creating a 10-term decreasing Geometric Series.

3. Create a Spreadsheet Window
Click on the +tool to activate this menu.

4. Add Column Headings
Move to the top of Column A and add this
column heading. Press Return.

5. Generate a Sequence for Column A
Highlight the Formula Cell for Column A.
Then press Menu and select Data >
Generate Sequence.

6. Generate a Sequence for Column A
You’ll be generating a 10-term Geometric Sequence with a
common ratio of 3. Configure the Sequence as shown here.
Press OK.

7. Generate a Sequence for Column A
You’ll see the sequence in Column A.

8. Generate a Decreasing Sequence
Now generate a second sequence by creating a column heading
in Column B. Press Return.

9. Generate a Decreasing Sequence
Press Menu and select Data > Generate Sequence.

10. Generate a Sequence for Column A
You’ll be generating a 10-term Geometric Sequence with a
common ratio of 1/3. Configure the Sequence as shown
here. Press OK.

11. Generate a Sequence for Column A
You’ll see the sequence in Column B.
