Which is the next prime number after 7?

Prime numbers are defined as natural numbers greater than 1 that have no positive divisors other than 1 and themselves. After identifying that 7 is prime, we look for the next number greater than 7 that meets these criteria.

The number 8 is not prime because it can be divided by 1, 2, 4, and 8, which means it has divisors other than itself and 1. Similarly, 9 is also not prime because it can be divided by 1, 3, and 9. The number 10 is not a prime number either; it can be divided by 1, 2, 5, and 10.

On the other hand, 11 is a prime number because its only divisors are 1 and 11, fitting the definition perfectly. Therefore, it is the next prime number after 7.
