Looks like two alternating sequences ..

6 , 6 , 6 , 12 , 12 , 24 , 18 , 48, (?)

In the bold sequence each term is created by adding up the previous two so I'd say 30 is the answer.

Thanks Guest55.
Brilliant. Correct answer.
The other sequence is not a Fibonacci,but just doubling.....I was baffled because of that.
