The pattern in the sequence is that each number is one less than a power of 2.

15 is 2^4 - 1
31 is 2^5 - 1
63 is 2^6 - 1
127 is 2^7 - 1
255 is 2^8 - 1

So the next number in the sequence should be one less than the next power of 2, which is 2^9 - 1 = 511.

So the sequence should be: 15, 31, 63, 127, 255, 511.
