COMMENTS
Without the restriction that no repeated digits are allowed (as in A297062), the sequence is infinite.
The smallest 10-digit term is 1023456789, the largest 10-digit term is 9876543210, and digits not contained in previous terms are introduced at n = 6, 15, 33, 129, 729, 5049, 40329, 362889.
EXAMPLE
a(6)=102 and not 110 since 102 < 110, hence the digit 2 is introduced at n=6.
