9. Geometric Sequences

10. Geometric Sequences
A sequence in which each term after the nonzero first term is found by multiplying the previous term by a common ratio

11. Geometric Sequences How do we find a common ratio for a sequence?
8, -2, (1/2), ...
Divide the second term by the first term:
-2/8
= -.25

12. Determine the common ratio and find the next three terms
Multiply the common ratio to find the next three terms
8, -2, (1/2), ...

13. Try this:
Determine the common ratio and find the next three terms: 2, 12, 72, ...

14. Try this: Determine the common ratio and find the next three terms:
2, 12, 72, ...

15. Try this…
Find the common ratio of the sequence
-164, -82, -41, -20.5…

16. Determine which sequence is geometric.
5, 11, 17, 23
4, -5, -14, -23
19, 2, 17, 4
2, 6, 18, 54
