Without looking at the solution I would count up from one. For every number that is not prime I would concatonate 10 to the right end of the string. For every number that is prime I would concatonate 1000 to the right end of the string.


10 10 1000 10 1000 10 1000 10 10 10 1000 10 1000

Usining this method the next 5 digits would be 10101.

OK just looked at the solution. Seems I had the right idea but not the right answer.
