 OFFSET 1,2 COMMENTS No term ends in 0 as this would force the next integer to start with zero. LINKS Carole Dubois, Table of n, a(n) for n = 1..5000 EXAMPLE The rightmost digit of a(1) = 1 is 1; we duplicate this digit in position 3; The rightmost digit of a(2) = 2 is 2; we duplicate this digit in position 5; The rightmost digit of a(3) = 11 is 1; we duplicate this digit in position 6; The rightmost digit of a(4) = 21 is 1; we duplicate this digit in position 8; The rightmost digit of a(5) = 3 is 3; we duplicate this digit in position 11; etc. CROSSREFS Cf. A336035 (duplication of the leftmost digit of a(n) to the left), A336036 (first and last digits of a(n) are duplicated respectively to the left and to the right).
