Definitely not Fibonacci Numbers or Even Numbers. This has to be something more specific, like Mersenne Primes.

Hmm, Mersenne Primes? Sounds like the right answer, but I'll have to double-check the formula.

I'm not sure, but I think it could also be B) Co-prime Numbers since the formula involves prime numbers.
