The interesting part of a solution of this kind of problem isn't the next number itself but how the next number is formed.
How can the next number of
1 3 5 7 11 13 17
be 19?
It could evidently not be every odd number starting from 1, where is 9 and 15?
So if the solution is 19, remembering that 1 is not a prime but 2 is, how is the serie formed?
