No luck yet ...

In binary: 01000000, 11110011, 100000000, 01111101
In hex: 40, F3, 100, 7D

8², ?, 16², 5³

Hmm...  good call MathIsFun.

But is this a pattern?  Can we just say 8² is next and it starts again?

Make sure we submit this to the On-Line Encyclopedia of Integer Sequences once we figure it out, 'cause it ain't there.
