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)

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. ;)
