The answer is 17.
The numbers in the sequence are all prime numbers, except for the missing number. The missing number must be a prime number that is greater than 13 and less than 23. The only prime number that satisfies these conditions is 17.
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.
