# What is the ratio (multiplier) for the following geometric sequence 8, 2, 0.5, 0.125.?

Jan 15, 2017

#### Answer:

The desired ratio is $\frac{1}{4}$ or $0.25$.

#### Explanation:

Common ratio (or multiplier) for a geometric sequence is the ratio between a term and its immediately preceding term and this is always same.

As $\frac{2}{8} = \frac{0.5}{2} = \frac{0.125}{0.5} = \frac{1}{4}$ or $0.25$

The desired ratio is $\frac{1}{4}$ or $0.25$.
