Find the missing term in the following series:
4, 6, 9, $13\tfrac{1}{2}$, ?
[A]$17\tfrac{1}{2}$
[B]19
[C]$20\tfrac{1}{4}$
[D]$22\tfrac{3}{4}$

$20\tfrac{1}{4}$
The pattern is $\times \frac{3}{2}$ So, missing number is $13\tfrac{1}{2}\times \frac{3}{2}=\frac{27}{2}\times\frac{3}{2}=\frac{81}{4}=20\tfrac{1}{4}$
