1. + 8.4 – Geometric Sequences

2. + Geometric Sequences A sequence is a sequence in which each term after the first is found by the previous term by a constant called the common ratio. geometric multiplying

3. + Find the first four terms of the geometric sequence with the given first term and common ratio. 1.

4. + Find the first four terms of the geometric sequence with the given first term and common ratio. 2.

5. + Explicit Formula Formula for the nth term of a geometric sequence:

6. + Find the specified term of the geometric sequence with the given first term and common ratio. 3.

7. + Find the specified term of the geometric sequence with the given first term and common ratio. 4.

8. + Common Ratio To find the common ratio, divide any term by its previous term: We can then use this common ratio and the explicit formula for geometric sequences to find terms in the sequence.

9. + Find the specified term of each geometric sequence. 5.

10. + Find the specified term of each geometric sequence. 6.

11. + Find the specified term of each geometric sequence. 7.

12. + State whether the sequence is arithmetic or geometric and then find the specified term. 8.

13. + State whether the sequence is arithmetic or geometric and then find the specified term. 9.

14. + State whether the sequence is arithmetic or geometric and then find the specified term. 10.
