ID Number: A028948
Sequence:  1,5,21,85,341,1365,2731,10927,5465,10933,1367,2735,10943,
           5473,10949,1369,2739,10959,5481,10965,1371,2743,10975,5489,

           1377,2755,11023
Name:      An "extremely strange sequence": a(n+1) = [ A*a(n)+B ]/p^r, where p^r
              is the highest power of p diving [ A*a(n)+B ] and p=2, A=4.001, B=1.2.

What's the connection, and why the parameters are just 2, 4.001 and 1.2 ?
