Correct answer: (C) 173
Two interwoven series alternate: 17, 29, 65, ? and 9, 21, 57. In the first series the difference triples each time (12, 36, 108), so 65+108=173. The second series confirms the pattern (12, 36).

सही उत्तर: (C) 173
दो अंतर्गुंथित शृंखलाएं हैं: 17, 29, 65, ? और 9, 21, 57। पहली शृंखला में अंतर हर बार तिगुना होता है (12, 36, 108), इसलिए 65+108=173। दूसरी शृंखला (9,21,57 - अंतर 12,36) इस पैटर्न की पुष्टि करती है।
