These numbers are increasing by 2^n.
The differences are:
2, 4, 8, 16...
The next differences would be 32, 64 and 128
So the next numbers would be:
63, 127, 255.

If you take the difference between each of the numbers in sequence, you see:
3-1=2; 7-3=4; 15-7=8; 31-15=16;...
so the sequence is:
2^0; 2^0+2^1; 2^0+2^1+2^2; ....

63, 127, 255
Every number is double its previus plus 1:
3 = 2*1 + 1
7 = 2*3 + 1
15 = 2*7 + 1
31 = 2*15 +1
e.t.c.
