Correct Answer: 200 


Solution : Given:
365, 364, 355, 330, 281, ?

Subtract the square of consecutive odd numbers from the previous term to get the next term of the series –
365 – 12 = 365 – 1 = 364;
364 – 32 = 364 – 9 = 355;
355 – 52 = 355 – 25 = 330;
330 – 72 = 330 – 49 = 281;
281 – 92 = 281 – 81 = 200

So, the missing number of the series is 200. Hence, the second option is correct.
