First we have to decode the pattern of this sequence.
As we can see that :-
6 = 3+3^1 (here 3 is the first number of the sequence)
15 = 6+3^2 , as we follow this pattern, Next expected number will be
15 + 3^3 = 15 + 27 = 42
Similarly, 42 + 3^4 = 42 + 81 = 123
Similarly, 123 + 3^5 = 123 + 243 = 366
Hence, the final answer is 42.
