1, 1, 2, 3, 5, 8
Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).
8 5 4 9 1 7 6 10 3 2 0 This sequence is special because the numbers are in alphabetical order. The Fibonacci sequence is very special and the triangular sequence.
If one may choose the break points, it looks like simple doubling: 3 - 6 - 12 - 24
That is a Fibonacci sequence with the starting numbers 2 and 6. 2 and 6 are stated, then the sequence is generated by each number being the sum of the last two: 2+6=8, 6+8=14, 8+14=22, 14+22=36 The next number will be 22+36, which is 58.
A Fibonacci series
The sequence S = 2, 2, 4, 6, 10, 16, 26, ... is the Fibonacci sequence multiplied by 2. Like the Fibonacci sequence, each term is found by adding the two previous terms, so Sn = Sn-1 + Sn-2.

1, 6, 11, 16 and 21
Ignoring the "9" , then this is a Fibonacci sequence. 2,2,4,6,10 The first two terms are 'seed' terms then successive terms equal the sum of the two previous terms. 2 + 2 = 4 2 + 4 = 6 4 + 6 = 10 The next term would be 6 + 10 = 16.
The missing numbers in the sequence 2 3 4 6 are 5 and 7.
