Correct Answer: $\frac{3}{16}$


Solution : Given:
$96,12, \frac{3}{2}, ?, \frac{3}{128}$

Multiply the previous term by $\frac{1}{8}$ to obtain the missing term in the given series.
$96×\frac{1}{8}=12;12×\frac{1}{8}=\frac{3}{2}; \frac{3}{2}×\frac{1}{8}=\frac{3}{16};\frac{3}{16}×\frac{1}{8}=\frac{3}{128}$

So, $\frac{3}{16}$ is the missing term in the given series. Hence, the fourth option is correct.
