3.11 Exercise 1

Avg difficulty 2.5

For each sequence, determine if the sequence is a geometric sequence. If so, identify the common ratio.

  1. {5,20,80,320,1,280,5,120,20,480,...}\left\{5 , 20 , 80 , 320 , 1,280 , 5,120 , 20,480 , ...\right\}
  2. {−3,6,−12,24,11,33}\left\{- 3 , 6 , - 12 , 24 , 11 , 33\right\}
  3. { 4,2,1,12,14,18,... }\left\{4 , 2 , 1 , \frac{1}{2} , \frac{1}{4} , \frac{1}{8} , ...\right\}
