Correct answer: (D) 92
The differences between consecutive terms increase by 2: 10, 12, 14, 16, 18. So the missing term = 80+12 = 92 (and 92+14=106 confirms it).

सही उत्तर: (D) 96 का
क्रमिक पदों के बीच अंतर हर बार 2 बढ़ता है: 10, 12, 14, 16, 18। अतः लुप्त पद = 80+12 = 92 है (और 92+14=106 इसकी पुष्टि करता है)।
