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

x=5.

Then, we know that x is a prime number.

x+1=5+1=6, which is not a prime number.

Thus, the required example is x = 5.
