Correct Answer: 488
Solution : Given: 512, 508, 500, 496, ?, 484
In the above-given series, subtract 4 and 8 alternatively from the previous numbers to get the next numbers. 512 – 4 = 508; 508 – 8 = 500; 500 – 4 = 496; 496 – 8 = 488; 488 – 4 = 484
So, 488 is the missing number of the given series. Hence, the third option is correct.
