In a geometric sequence, the ratio between consecutive terms is constant. This ratio is called the common ratio. To find r:

4
Geometric, Arithmetic, Neither? (find the next 2 terms if so) 1. 5, 15, 45, 135… 2. 15, 30, 45, 60… 3. 6, -24, 96, -384… 4. 8, 20, 32, 44…

5
Geometric Sequences Formulas Recursive Formula a n = a n-1 r Explicit Formula a n = a 1 r n-1

6
Find the 19 th term… 1. 11, 33, 99, 297… 2. 20, 17, 14, 11, 8…
