Question 35

Complete the series.
48, 24, 72, 36, 108, (…)

Solution

Numbers in the given series are alternately divided by $$2$$ and multiplied by $$3$$.

i.e., $$\frac{48}{2}$$ = $$24$$

$${24}\times{3}$$ = $$72$$

$$\frac{72}{2}$$ = $$36$$

$${36}\times{3}$$ = $$108$$

Required number = $$\frac{108}{2}$$ = $$54$$.
