Question

what is the smallest prime number of the form 3k+1​

Answer 1

Answer:

5 is clearly the smallest prime belonging to two such pairs (3, 5) and (5, 7). Let p ≥ 7 be a prime. p has to either be of the form 3k +1 or 3k + 2 for some k ≥ 2. If p is of the form 3k + 1, then p +2=3(k + 1) cannot be prime, and if p is of the form 3k + 2, then p − 2=3k cannot be prime
