In finding the nth term of a geometric sequence use the formula an = a₁-1 where A is the last term, a, is the last term and r is the common ratio.

Activity 2: Directions: Solve the following problems.

1. If the first term of a geometric sequence is 2 and the common ratio is 3, determine a..

2. Determine the 7th term of the geometric sequence 512, 256, 128, ...

3. If a = 6 and a; = 18, determine the 9th term.

4. What is the sixth term of the geometric sequence .2.10...? 25

5. Determine the 10th term of the geometric sequence if the third term is 12 and the sixth term is 96.​
