• a(n) = 3*a(n-1)+4 for n > 0; a(0) = 6.at n=12A171495
• a(n) is the smallest positive integer k such that for all x >= k, at least 50% of the integers in the range 1..x contain n in their decimal expansion. In other words, it is the largest integer k such that exactly half of the integers 1..k have n in their decimal expansion.at n=4A346685
