Since there hasn’t been a sequence yet on the other thread dealing with numbers as numbers (as opposed to stand-ins for subway stops, speech patterns, and whatnot), I thought I’d start a thread which restricted the number sequences to their numerical properties.
Whoever guesses the next number in one sequence correctly (with explanation) gets to provide the next one.
alternate answer = 47
This will work if, and only if, you consider 1 to be a prime number (which it really isn’t). The sequence goes like this: name a prime number, skip 1 prime #, name another prime #, skip 2 prime #'s, name the next prime #, skip 3 prime #'s, etc.
Damn, wait, if you consider 1 a prime number, then 2 would have to be considered prime as well, which throws the whole thing off. Oh, well. It holds if you start at five and skip two primes.

2 is prime. **

yep, you’re right. Would have worked if FTfirefly had replaced 1 with 2. Oh well. Who gets to post the next series?
Interesting or not, it didn’t give the answer I was looking for. The formula is much simpler than whatever the Hades “Self-complementary 2-multigraphs with loops on n nodes.” is.
