Two possible answers spring immediately to mind. First, this sequence appears to be a list of the first five prime numbers; in this case, the next number in the sequence would be 13. Second, the intervals between these numbers comprise the sequence "1 2 2 4", in which the nth number equals the product of the (n-1)th and (n-2)th numbers. Based on this, the next number in the given sequence would be 11 + (4*2) = 19.

1 2 3 5 7 11 13 15 what is the next number in the sequence and why?
23
What number comes next in this sequence 1 3 6 11 18 29?
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
What is the next number in the sequence 2 3 5 7 11 13?
These are all prime numbers. The next one is 17
What are the next 2 numbers in the following sequence 2 3 5 7 11?
This list of numbers is the list of prime numbers. Following 11, the next two numbers in the list are 13 and 17.
What is next in the sequence 1 10 3 9 5 8 7 7 9 6?
1+10 - 2 (2 is one less than 3, the next answer in the sequence) = 9. 10 + 3 - 8 (8 is one less than 9) = 5 3 + 9 - 4 = 8 etc...; so the next two numbers in the sequence will be 11 and 5.
