Solution :-
If you closely see the series, you will find that there is a definite pattern. The numbers are multiplied by the prime numbers. 1st number is multiplied by 2, 2nd is multiplied by 3, 3rd number is multiplied by 5 and so on.
0.5, 1, 3, 15, 105, 1155, ?
0.5*2 = 1
1*3 = 3
3*5 = 15
15*7 = 105
105*11 = 1155
1155*13 = 15015
So, the next number in the given series is 15015.
