Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.
4 2 2 3 6 15 ?
A45
B18
C20
D25
Answer: Option A
Explanation:by dividing second digit to first digit we get this : 1/2, 1, 3/2, 2, 5/2, so there one gap is 1/2,3/2,5/2 and other is 1,2 so the next gap will be 3.
4 * 1/2 = 2
2 * 1 = 2
2 * 3/2 =3
3 * 2 = 6
6* 5/2=15
15 * 3 = 45
