Even Number=Multiply by 3
Odd Number=Multiply by 3 and add 1
Then halve

ans is- 54,27.
If you see the sequence of numbers you will realize that there are 2 alternate sequences in the riddle;

The first sequence has 2 possibilities, in case of an odd number you multiply by 3 and add 1 and in case of even number you just multiply by 3.

The second sequence is we divide the previous number by 2.

when you are in first sequence, and if u get  oddnumber then multiply by 3 and then add by 1,
as shown-3*3+1=10
5*3+1=16
But logic is not consistent, same can not be applied on later part

and agr even number h then only multiply with 3, this is logic ,
