What is the next prime number after 7?

The next prime number after 7 is 11. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. After 7, the numbers 8, 9, and 10 are all not prime because they can be divided evenly by numbers other than one and themselves. For example, 8 can be divided by 1, 2, 4, and 8; 9 can be divided by 1, 3, and 9; and 10 can be divided by 1, 2, 5, and 10.

However, when we reach 11, we find that it can only be divided by 1 and 11, confirming that 11 is indeed a prime number. Therefore, it is the next prime number following 7.
