Answer is Right!
Answer is Wrong!
The missing number is 11.
The numbers in the sequence are all prime numbers, except for 10, which is a composite number. The next prime number after 10 is 11.
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A composite number is a natural number greater than 1 that is not prime.
