Question

What is the common ratio for the geometric sequence? 24, -6, 3/2, -3/8, ...

Answer 1

Answer:

-1/4

Step-by-step explanation:

Use the formula: a2 divided by a1. (a2/a1)

Plugging it in would look like this:

-6/24

-6/24 is equal to -1/4.

Hope this helps!

Answer 2

Answer:

$-\frac{1}{4}$  is the common ratio.

Step-by-step explanation:

A sequence is a set of things (usually numbers) that are in order.

In a Geometric Sequence each term is found by multiplying the previous term by a constant.

For a geometric sequence, the common ratio is the ratio of a term to the previous term.

Given the geometric sequence $24, -6, \frac{3}{2}, -\frac{3}{8} , ...$

To find the common ratio, find the ratio between a term and the term preceding it.

$r= -\frac{\frac{3}{2}}{6} =-\frac{3}{12}=-\frac{1}{4}$

$-\frac{1}{4}$  is the common ratio.
