That's prime. Can someone figure out what's actually going on here? Prime numbers with that many digits shouldn't pop up by pure chance... I'm sure you all caught this, but the first 3 in the sequence are also prime.

I'm too busy to check but I'd bet money that it's a Mersenne prime. The series looks exponential (like 2^n) and it's not hard to imagine that fenceposting (±1) led to each member in the series being (2^n)-1 - which is the form for Mersenne primes. Edit: Dang, I was wrong. ;)
