Is there a rule governing the frequency of prime numbers?
Also, I've heard that all primes greater than 3 are of the form 6k+1 or 6k-1. I'm assuming that this is because 6 is the lcm of 2 and 3 (the two primes lesser than 3), and the +1,-1 is because if the number was in a range greater than 1 around the 6k number, it should be a multiple of 2 (even number).
Can you extend this for any primes greater than any given prime (say 5 instead of 3 for example) ?
