Abstract

top
In this paper we give a recursive formula for the sequence of primes { p n } and apply it to find a necessary and sufficient condition in order that a prime number p n + 1 is equal to p n + 2 . Applications of previous results are given to evaluate the probability that p n + 1 is of the form p n + 2 ; moreover we prove that the limit of this probability is equal to zero as n goes to . Finally, for every prime p n we construct a sequence whose terms that are in the interval [ p n 2 - 2 , p n + 1 2 - 2 [ are the first terms of two twin primes. This result and some of its implications make furthermore plausible that the set of twin primes is infinite.

AB - In this paper we give a recursive formula for the sequence of primes $\{p_n\}$ and apply it to find a necessary and sufficient condition in order that a prime number $p_{n+1}$ is equal to $p_{n}+2$. Applications of previous results are given to evaluate the probability that $p_{n+1}$ is of the form $p_{n}+2$; moreover we prove that the limit of this probability is equal to zero as $n$ goes to $\infty$. Finally, for every prime $p_n$ we construct a sequence whose terms that are in the interval $[p_n^2 - 2 , p_{n+1}^2-2[$ are the first terms of two twin primes. This result and some of its implications make furthermore plausible that the set of twin primes is infinite.
