%N Lengths of the loop of the sequences "Sum of last n digits" beginning with (n-1) zeros followed by digit 5.
%e a(4)=50 because the sum of last four *digits* of the sequence beginning with 0,0,0,5, (three zeros followed by a 5) enters in a loop whose length is 50 terms; so a(4)=50
%e a(5)=63 because "Sum of last five digits" beginning with 0,0,0,0,5 enters in a cycle of 63 terms.
