AI explanation

The series follows a pattern of alternating addition and subtraction of consecutive square numbers. Adding 1 squared to 1999 gives 2000, subtracting 2 squared from 2000 gives 1996, adding 3 squared to 1996 gives 2005, and subtracting 4 squared from 2005 gives 1989. Following this pattern, you add 5 squared to 1989 to get 1989 + 25 = 2014.
