Explanation

The pattern alternates between subtracting 4 and subtracting 2: 17-4=13, 13-2=11, 11-4=7, 7-2=5, 5-4=1, 1-2=-1.

AI explanation

The series follows a pattern of subtracting consecutive prime numbers in descending order. Starting from 17, subtracting 4 gives 13, subtracting 2 gives 11, subtracting 4 gives 7, subtracting 2 gives 5, and subtracting 4 gives 1. Continuing this repeating cycle of subtracting 4, then 2, the next operation is 1 minus 2, which equals -1.
