Why do you add 1 to the list? I still don’t understand that part of the logic..

How did you know to set out the question with the list of primes +1, eg if i get a different question with similar type of working how will i know how to lay out my answer to prove the contradiction?

This took me so long to figure out, thanks for all your help. Gained a new suscriber!

Just tell them the list of primes is endless because the lowest factor greater than 1 of p!+1 must be a prime number and must be greater than p. And tell them it is not actually a 'proof by contradiction'.
