To be pedantic, the question should say "for all n >= 2". A detailed proof is given here: http://mathforum.org/library/drmath/view/51527.html The proof is quite long, but it only uses properties of logarithms, exponents, and the binomial theorem, so if you know about these and have enough mental stamina, you can probably make sense of it.
The notation 2N typically means double the amount of a variable or object N. So, 2N is twice the value of N.
Meiosis is a type of cell division that results in the formation of gametes (sperm and egg cells) in sexually-reproducing organisms. The process involves one round of DNA replication followed by two rounds of cell division, producing cells with half the chromosome number (n). This leads to genetic variation and ensures the correct chromosome number is maintained in the offspring.
represents the diploid number of chromosomes turning into the haploid number of chromosomes during meiosis, in the production of gametes

Diploid is designated as 2n, representing two sets of chromosomes in a cell. Haploid is designated as n, representing one set of chromosomes in a cell.
Prime if n=1, composite otherwise.
2 is a prime number. 2 times anything but 1 is composite.
make n one
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.
The notation 2N typically means double the amount of a variable or object N. So, 2N is twice the value of N.
2n is 2 times n.
The proof relies on a result from number theory known as the Bertrand's postulate, which states that for any integer ( n > 1 ), there exists at least one prime ( p ) such that ( n < p < 2n ). Since ( n! ) (n factorial) grows much faster than ( 2n ) for ( n > 2 ), we can conclude that there are primes not only between ( n ) and ( 2n ) but also between ( n ) and ( n! ). Thus, for any integer ( n > 2 ), there exists a prime ( p ) such that ( n < p < n! ).
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.
To prove that 2n1 o(2n), we need to show that the growth rate of 2n1 is strictly less than the growth rate of 2n as n approaches infinity. This can be demonstrated by using the formal definition of little-o notation and showing that the limit of (2n1) / 2n as n approaches infinity is equal to 0.
2n can be split into 2 n's so: n+n then add one to one of the n's and subtract one from one of the n's n+1+n-1 ^two consecutive odd integers^
Meiosis produces haploid gametes which have the ' n ' symbol.
A Mersenne number is a number of the form 2n-1. When this number is prime, it is known as a Mersenne prime.A Mersenne prime has the form 2n-1. For 2n-1 to be prime, n must also be prime. Examples are the Mersenne prime 7 (23 - 1 = 7) and the Mersenne prime 127 (27 - 1 = 127)
