Final answer:
Without additional context, it is not possible to decipher the pattern or sequence related to the question regarding benches on the station platform. The query requires rules or a cipher key which is not provided.
Step-by-step explanation:
The question seems to involve a pattern or sequence puzzle, potentially related to a coding or substitution cipher where numbers are meant to correspond to something else, possibly letters or positions. However, since the question does not provide enough context or a clear set of rules for decoding the sequence of numbers given or understanding the content between the parentheses '(17-190)', it is not possible to provide a definite answer.
The sequence and the numbers given outside of the context, do not seem to apply to standard mathematical operations or recognizable sequences that can be deciphered without additional information. The answer choices (17, 18, 19, 20) do not seem to directly correspond to any evident patterns within the provided numbers.
