Big sigh....
so the fifth number should indeed have been 52 not 49.
In that case the next number is 62.
The sequence is numbers n such that:
1 + n + n^3 + n^5 + n^7 + n^9 + n^11 + n^13 + n^15 + n^17 + n^19 + n^21 + n^23 + n^25 + n^27 + n^29 + n^31 + n^33 + n^35 is prime.
The first few terms are:
1, 7, 10, 17, 52, 69, 108, 161, 173, 231, 306, 330
