To determine the pattern in the series 17, 20, 14, -1, we can see that the difference between each consecutive number is not consistent. The sequence seems to be alternating between adding and subtracting numbers. Specifically, the pattern is +3, -6, -15. Following this pattern, the next number in the series would be obtained by subtracting 24 from -1, resulting in -25.
The next set in the pattern would be 5 to 22. The pattern is to increase the first digit by 1, second digit by 2.

The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
The pattern is plus 7. So the next number used to be 1.
