Geometric Sequences · Exercise 1

Determine if each sequence is geometric. If so, indicate the common ratio.

$-150$, $-30$, $-15$, $-5$, $–\frac{5}{2}$, …

$$\begin{array}{cc}\text{Find the ratio of consecutive terms.}& \\ & \end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
