A Mersenne prime has the form 2n-1. For 2n-1 to be prime, n must also be prime. Perfect numbers have the form 2n-1(2n-1) where 2n-1 is a Mersenne prime, so when a new Mersenne prime is discovered, another perfect number is also found.


What are Mersenne Primes used for?

Mersenne primes are mostly of interest as mathematical curios. A Mersenne prime has the form 2n-1. For 2n-1 to be prime, n must also be prime. Perfect numbers have the form 2n-1(2n-1) where 2n-1 is a Mersenne prime, so when a new Mersenne prime is discovered, another perfect number is also found.


How do you prove that there is a prime between n and 2n?

One way to prove that there is a prime between n and 2n is to use contradiction. Assume there are no primes between n and 2n. Then, all numbers between n and 2n are composite. However, by multiplying all primes smaller than or equal to n, you obtain a number more significant than n, which contradicts the assumption.
