# How do you find the next two terms of the geometric sequence 1.25, -1.5, 1.8,...?

$- 2.16 , 2.592$

#### Explanation:

To find the ratio between two consecutive terms, divide the second term by the first term.

$- \frac{1.5}{1.25}$
$- 1.2$

To find the next two terms, multiply the last term by the ratio.

$1.8 \cdot - 1.25$
$= - 2.16$

And to find the final term, repeat the process

$- 2.16 \cdot 1.25 = 2.592$
