 Interesting Sequence (5) (Posted on 2004-11-07)
1, 3, 5, 7, 9, 15, 17, 21, 27, __, __, __, ...

What are the next three numbers in this sequence?

 Submitted by SilverKnight Rating: 4.3333 (6 votes) Solution: (Hide) 31, 33, 45. Each number is the decimal value for the sequence of palindromic binary numbers, starting with (and finishing with) a 1. ie. 1=1, 3=11, 5=101, 7=111, 9=1001, 15=1111, 17=10001, 21=10101, 27=11011, 31=11111, 33=100001, 45=101101.
