Correct Answer: 3367
Solution : Given: 3, 7, 5, 61, 363, ?
Multiply numbers by odd numbers and add and subtract the square of even numbers alternatively, to get the required missing number – 3 × 1 + 22 = 3 + 4 = 7; 7 × 3 – 42 = 21 – 16 = 5; 5 × 5 + 62 = 25 + 36 = 61; 61 × 7 – 82 = 427 – 64 = 363; 363 × 9 + 102 = 3267 + 100 = 3367
So, 3367 is the required missing number. Hence, the first option is correct.
