Correct Answer: 256


Solution : Given: 

  4    8    16
  32   64   128
  ?  512  1024

In the second column, 23 = 8, 26 = 64, 29 = 512. Here, 3, 6, and 9 are in AP.

In the third column, 24 = 16, 27 = 128, 210 = 1024. Here, 4, 7, and 10 are in AP.

In the third column, 22 = 4, 25 = 32. The next number in the power of two will be 8.

So, the missing number is 28 = 256.

Hence, option fourth is correct.
