The answer is Option C that is 255 The difference from 3 to 7 is 4. The different from 7 to 15 is 8. The difference from 15 to 31 is 16. The difference from 31 to 63 is 32. The observation if 4 X 2 = 8, 8 X 2 = 16. Like wise, we can find next ones also. Only 5 are given and we have to find the 7th one. So, let is first find the 6th one. 32 X 2 = 64. So, 63 + 64 = 127. The 6th number is 127. Now, we have to find the 7th one. 64 X 2 = 128. 127 + 128 = 255. That is Option C
