are you sure you have the sequence right? from that sequence it must be 12 because it's just adding two each time, which is far too simple, is the 8 meant to be there?
if it was 1, 2, 4, 6, 10, then the next number is also 12 as they are all primes - 1, but it is at least a slightly harder sequence to figure out.
(it's also close to the burnt pancake sequence which would be 1 ,4, 6, 8, 10, though the next number is still 12)
the sequence is a tie breaker in a name quiz and it is definately1.2.4.6.8.10 ? so as it is a tiebreaker I think everyone will put twelve so I think it is something different, thanks for your help
4, 6, 10 and 12 aren't primes. Would agree that next number would be 12 unless the numbers refer to something less obvious like those sequences that list the number of letters in each month or something
