Answer: 11
It's a list of prime numbers
Q:
.....since when is 9 a prime number?
Answer: 17
It's not a list of primes, it's not a Fibonacci sequence. The only pattern I see is that the last number in the sequence gets a number added to it to produce the next number in the sequence, the number that's added doubles each time. E.g. 2+1 = 3 (1 is added)
3+2 = 5 (1 is doubled = 2, then added)
5+4 = 9 (2 is doubled = 4, then added)
9+8 = 17 (4 is doubled = 8, then added)

33
17
2+3=53+5=85+8=1313+21=3333 is the next number in this pattern. This pattern is called a Fibonacci.
13, because if you add the last number to the current number you get the next number
The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.
