What are the next two numbers in the following series?
2, 3, 5, 11, 23, 29, 41, 53, _ , _ .
Also mention the rule that the numbers follow.

series idea.. by Paul)
Well, I haven't looked yet at SK's solution. Looking at your comment, I don't think that the ommited numbers have anything to do with adding previous numbers. It could easily be a coincidence. Many prime numbers are only two away from each other and 2 is a prime number.
Maybe numbers are skipped because of their place in the series of primes. The numbers 4, 6, 7, 8, 9, 12, 13, 15, and 16 are all skipped. We might have to find a pattern there. We may also have to find a pattern in which ones were not skipped, or the numbers skipped, as you tried to do.
