3, -6, 12, 4, 20, ?
3. Ignore the 8's in the sequence and you get 9, 6, 4, 3,_. 9-3=6 6-2=4 4-1=3 3-0=3

6
The next number in the sequence is 18. It's +1, +2, +3, +4, ....

The rule for this sequence appears to be adding consecutive prime numbers. The sequence starts with 3, then adds the next prime number 2 to get 4. It then adds 3 (the next prime number) to 4 to get 7, then 5 to 7 to get 12, and so on. Each number in the sequence is the sum of the previous number and the next prime number in order.
