Definition
The sequence of Thabit numbers begins:
- $2, 5, 11, 23, 47, 95, 191, 383, 767, 1535, 3071, 6143, 12287, 24575, 49151, 98303, \ldots$
This sequence is A055010 in the On-Line Encyclopedia of Integer Sequences (N. J. A. Sloane (Ed.), 2008).
Note that the OEIS prefers to start the sequence with a leading $0$, but this feels counterintuitive.
