If you add one to a prime then it will definitely NOT be prime. Unless the prime number is 2.

 

This is becasue 2 is the only EVEN prim number.

All other prime numbers are odd.

so

if you add 1 to any of them you will have an even number and the only even number that is prime is 2!

 

You may find this interesting :)
