Correct Answer: 99
Solution : Given: 35, 50, 63, 82, ?, 122
Alternately subtract and add 1 to the squares of consecutive natural numbers, starting with 6, to get the required missing number. (6)2 – 1 = 36 – 1 = 35; (7)2 + 1 = 49 + 1 = 50; (8)2 – 1 = 64 – 1 = 63; (9)2 + 1 = 81 + 1 = 82; (10)2 – 1 = 100 – 1 = 99; (11)2 + 1 = 121 + 1 = 122
So, the required missing number is 99. Hence, the second option is correct.
