Answer is Right!
The answer is 7.
The numbers in the sequence are the first 10 prime numbers, starting with 2. The missing number is the 7th prime number, which is 7.
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.
The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
