Correct answer: (C) 113
Differences: 57−53=4, 65−57=8, 77−65=12, 93−77=16 (differences increase by 4 each time: 4,8,12,16). Next difference = 20. So next term = 93+20 = 113.

सही उत्तर: (C) 113
अंतर: 57−53=4, 65−57=8, 77−65=12, 93−77=16 (अंतर हर बार 4 से बढ़ रहे हैं: 4,8,12,16)। अगला अंतर = 20। अतः अगला पद = 93+20 = 113।
