 OFFSET 1,1 COMMENTS To divide a(n) by (9 + n), merely shift the leftmost digit of a(n) to the end of a(n) and erase the next digit. The sequence is finite: there are no numbers having this property that start with 20,21,22,23,24,...97,98,99. LINKS Jean-Marc Falcoz, Table of n, a(n) for n = 1..10 EXAMPLE To divide a(1) = 1010 by 10, just shift the first digit 1 to the end and erase 0 (which gives 101 -- and, indeed, 101*10 = 1010). To divide a(4) = 13100775193798449612403 by 13, just shift the first digit 1 to the end and erase 3 (which gives 1007751937984496124031 -- and, indeed, 1007751937984496124031*13 = 13100775193798449612403).
