Correct Answer: 252
Solution : Given: 87, 168, 217, 242, 251, ?
In the above-given series, add squares of consecutive odd numbers in descending order to the numbers. 87 + (9)2 = 87 + 81 =168; 168 + (7)2 = 168 + 49 = 217; 217 + (5)2 = 217 + 25 = 242; 242 + (3)2 = 242 + 9 = 251; 251 + (1)2 = 251 + 1 = 252
So, the missing number of the series is 252. Hence, the third option is correct.
