It would seem to be 11.
-------------------------------------
Here are a couple of ways to justify the answer "11":
#1:
2 -> 6 is an increase of 4.
6 -> 3 is a decrease of 3.
3 -> 8 is an increase of 5.
8 -> 6 is a decrease of 2.
6 -> 12 is an increase of 6.
12 -> 11 is a decrease of 1.
#2:
2 -> 3 is an (odd) increase of 1.
6 -> 8 is an (even) increase of 2.
3 -> 6 is an (odd) increase of 3.
8 -> 12 is an (even) increase of 4.
6 -> 11 is an (odd) increase of 5.

No, you won't see anything more there. It is just that Merge is playing up so I had to copy the whole answer across!

The Fibonacci sequence is a sequence of numbers where each number in the sequence is the sum of the two numbers right before it. for example: 11235812 <-------Fibonacci Sequence 1 1+1=2 1+2=3 2+3=5 3+5=8 5+8=12
Prime number sequence.

The number that completes the sequence would be 11. Imagine the sequence as two sequences of every other number starting with the first 2 and the first 6. You would have 2 3 6 and 6 8 12 2 3 6 is adding odd numbers starting with one. 6 8 12 is adding even numbers starting with two. The next number belongs to 2 3 6 so you would add 5 to get 11.
2 (+4) --> 6 6 (-3) --> 3 3 (+5) --> 8 8 (-2) --> 6 6 (+6) --> 12 The next number would have been 12 (-1) --> 11 ===============
