<P><FONT size=2>Hello SeqFans,<BR>to compute the next term, add to n the term t
-- t being the<BR>quantity of [last digit of n] used so far in the
sequence.</FONT></P>
<P><FONT
size=2>0,1,2,3,4,5,6,7,8,9,10,12,14,16,18,20,23,25,27,29,31,38,41,49,52,</FONT></P>
<P><FONT size=2>Example:</FONT></P>
<P><FONT size=2>0,1,2,3,4,5,6,7,8,9,10,12</FONT></P>
<P><FONT size=2>What follows 12?</FONT></P>
<P><FONT size=2>Make 12 + (2 = quantity of "2" used so far in the seq.) =
14</FONT></P>
<P><FONT size=2>What follows 31?</FONT></P>
<P><FONT size=2>Make 31 + (7 = quantity of "1" used so far in the seq.) =
38</FONT></P>
<P><FONT size=2>----</FONT></P>
<P><FONT size=2>At any moment you can check how many digits of a certain
kind<BR>are used so far in the seq. with a simple substraction:</FONT></P>
<P><FONT size=2>- Take two consecutive integers, say 49 and 52; substract
them:<BR>52-49=3; there are three "9" used so far in the seq.</FONT></P>
<P><FONT size=2>- If you want to know, say, how many "7" are used in the
range<BR>0--52, go down from 52 to the first "7" (in "27"), substract<BR>27 from
the next term (29) and you have the answer : two "7"<BR>are used between 0 and
52.</FONT></P>
<P><FONT size=2>----</FONT></P>
<P><FONT size=2>Could someone extend the seq if of interest?</FONT></P>
<P><FONT size=2>Best,<BR>E.</FONT></P>
