COMMENTS

Breaks down when 93250 (base 14) = 25DAA.

LINKS

Table of n, a(n) for n=1..12.

FORMULA

a(1) = 2 (base 10) = 10 (base 2); for n>1: a(n+1) = the base (10) interpretation of a(n), evaluated in base (n+1).

EXAMPLE

a(2) = 101 because a(1) = 2 (base 10) = 10 (base 2) and 10 (base 3) = 101.

a(3) = 1211 because a(2) = 101 and 101 (base 4) = 1211.

a(4) = 14321 because a(3) = 1211 and 1211 (base 5) = 14321.

a(5) = 150145 because a(4) = 14321 and 14321 (base 6) = 150145.
