WebJul 21, 2024 · This shows that there are arbitrarily long prime gaps, and so out along the list of natural numbers there are places where the closest primes are 100, or 1,000, or even 1,000,000,000 numbers apart. A classic tension can be seen in these results. There are infinitely many prime numbers, yet consecutive primes can also be infinitely far apart. WebFermat numbers. The number 2^ (2^n)+1 is denoted by F_n. Only five of these. numbers (F_0 thru F_4) are known to be prime. Numbers of the form b^ (2^n)+1 (where b is an integer greater than 1 and n is. a non-negative integer) are known as generalized Fermat numbers, and they. are sometimes prime.
