According to the meaning of the question, the sum of four digits plus 1 has the following rules: (1) if there is no carry, then the sum of four digits = the sum of original digits + 1 = 18 or 35, which cannot be divisible by 17; (2) if there is a carry, then the sum of four digits = the sum of original digits + 1 - (10-1) = 9 or 26, which cannot be divisible by 17
