3 is what I think the answer would be. 3 + 1 is 4, 4 is not a prime number, 3 is prime.

Answer:  The required example is x = 5.

Step-by-step explanation:  Given that if x is a prime nu mber, then x+1 is not a prime number.

We are to give a counterexample for this.

Let us consider that

[tex]x=5.[/tex]

Then, we know that x is a prime number.

But, we get

[tex]x+1=5+1=6,[/tex] which is not a prime number.

Thus, the required example is x = 5.
