Since you can't possible think of some random 2000 consecutive composite integers, you need to think of some relation or formula. Here's a sequence of 2000 consecutive composite numbers - 2001! + 2, 2001! + 3, 2001! + 4,.........,2001! + 2001 consists of all composite numbers. In the sum 2001! + x, we can see that both 2001! and x are definitely divisible by x as long as x < 2001. Note- this can be used to create a sequence of N number of composite integers.
