In what context has the question arisen? Knowing that might point us in the right direction.
There is a known mathematical sequence which begings 1, 7, 10, 17- but the next term is 52 not 49. Are you sure of all the numbers- posters have been known to make a slip sometimes when posting questions?
Sorry if I've killed off another PK123 thread. Perhaps we'll never know the answer
Did you ever find the answer, PK123?
Maybe one of those text answering services could help?

Funnily enough I noticed one of PK's questions was listed on that AQA link in the other thread

sorry 52
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
sorry 69 :-)
