Find the next number in the number series:
48, 24, 72, 36, 108,?

Correct option is D

Given:
Given series 48,24,72,36,108
Solution:
The terms of series can be decoded as
$$\frac{48}{2} = 24$$​
$$24 \times 3 = 72$$​
$$\frac{72}{2} =36$$​
$$36 \times 3 = 108$$​
$$\frac{108}{2} = 54$$​
So the next number is 54 in the series
Hence correct option is (d)
