6.4 It’s Geometric
Cool Down: 5 minutes
Student Task Statement
A geometric sequence starts 12, 6, . . .
1. Write a recursive de nition for this sequence.
2. Sketch a graph representing the rst ve terms of the sequence.
Student Response
1. for 2. see graph
Student Lesson Summary
Here are some ways to represent a sequence. Each representation gives a di erent view of the same sequence.
• A list of terms. Here’s a list of terms for an arithmetic sequence: . We can show this sequence is arithmetic by noting that the di erence between consecutive terms is always 3.
• A table. A table lists the term number and value for each term. It can sometimes be easier to detect or analyze patterns when using a table.
