Zak,
<< Anyone has a clue? >>
I frequently feel clueless, but not this time. (I guess that means this
problem is special.) ;-)
Start with a(1) = 185 (because it's special <g>);
then a(n+1) = a(n), taken as a base-10 number and converted to base (b(n)+1)
where b(n) = the largest digit of a(n)
E.g.,
largest digit in 185 is 8, and 185 (base 10) converted to base 9 is 225;
largest digit in 225 is 5, and 225 (base 10) converted to base 6 is 1013;
largest digit in 1013 is 3, and 1013 (base 10) converted to base 4 is 33311
....
Did I get it right?
