What is the next prime number after 7?

What is the next prime number after 7?

• A. 9
• B. 10
• C. 11
• D. 13

Answer: (C)

The next prime number after 7 is 11 because a prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. Starting from 8, we can evaluate the numbers sequentially. - 8 is divisible by 1, 2, 4, and 8, so it is not prime. - 9 is divisible by 1, 3, and 9, so it is also not prime. - 10 is divisible by 1, 2, 5, and 10, which means it is not prime. - However, when we reach 11, the only divisors are 1 and 11, confirming that it is prime. Therefore, 11 is the next prime number following 7.
