Correct Answer: 294

First differences: 14, 30, 52, 80; second differences: 16, 22, 28 (+6 each); next second difference 34 → next first difference 114 → 180 + 114 = 294. (288 is the trap of missing the +6 step.) / प्रथम अंतर: 14, 30, 52, 80; द्वितीय अंतर: 16, 22, 28 (प्रत्येक +6); अगला द्वितीय अंतर 34 → अगला प्रथम अंतर 114 → 180 + 114 = 294। (288 जाल है — इसमें +6 चरण छूटा है।)
