Find the missing term in the following series.

1)

 4, 6, 9, $13\frac{1}{2}$, ?


A) $17\frac{1}{2}$

B) $20\frac{1}{4}$

C) $22\frac{3}{4}$

D) 19

Answer:

Option B

Explanation:

The pattern is × $\frac{3}{2}$. So, Missing number = $13\frac{1}{2}$ × $\frac{3}{2}$ = $\frac{27}{2}\times\frac{3}{2}$

$\frac{27}{2}\times\frac{3}{2}$ = $\frac{81}{4}$ = $20\frac{1}{4}$.

Hence the answer is (b).
