Question

Help me understand this question: Let P(n): n and n+2 are primes. be an open sentence over the domain N. Find six positive integers n for which P(n) is true. if n ∈ N such that P(n) is true, then the two integers n, n+2 are called twin primes. it has been conjectured that there are infinitely many twin primes.

Answer 1

What you want to do is continue to sieve through the primes or alternatively have a program sieve through them and pick out n and n+2 primes.

Answer 2

can you give me an example?

Answer 3

3 and 5 are twin primes, since both are prime and 5 = 3+2

Answer 4

11 and 13 are both prime and 13 = 11+2

Answer 5

Thank you Wio.
