1. Select all sequences that could be geometric.
A. 2, 4, 7, 11,...
B. ,1,3,9,...
C. 1, 3, 5, 7, ...
D. 1, 2, 8, 32, ..
E. 1,000, 200, 40, 8,
F. 999, 899, 799, 699,...

B and E

Step-by-step explanation:

Geometric sequences increase or decrease by the same multiple between successive terms.

B => from one term to the next we multiply by 3, i.e. 1 x 3 = 3, then 3 x 3 = 9, then 9 x 3 = 27 and so on

E => here we multiply by 1/5, i.e. 1000 x 1/5 = 200, then 200 x 1/5 = 40, then 40 x 1/5 = 8 and so on.
