## jennyjewell25 Group Title Is the sequence 3, 12, 36, ... a geometric sequence? Explain 2 years ago 2 years ago

1. saifoo.khan

Use the formula to find out it's rate.

2. jennyjewell25

what lol

3. saifoo.khan

$\frac{12}{3} = 4$ $\frac{36}{12}=3$ So their signs rate is different hence it means they aren't geometric.
