Options

• $$-\frac{4}{3}$$

• $$-\frac{2}{3}$$

• $$\frac{2}{3}$$

• $$-\frac{3}{8}$$

Answer 1

The common ratio of the G.P. $$-\frac{3}{4}, \frac{1}{2}, -\frac{1}{3}, \frac{2}{9}, ......$$ is `underlinebb(-2/3)`.

Explanation:

Dividing the second term by the first gives $$\frac{1/2}{-3/4} = -\frac23$$, which is the common ratio.
