 Hints (Greetings from The On-Line Encyclopedia of Integer Sequences!)
 A098289 Let a(1)=0. Then a(i+1)=position of first occurrence of a(i) in decimal expansion of log 2. 18
 0, 9, 2, 22, 419, 591, 898, 915, 285, 3618, 10367, 5396, 1192, 8251, 13198, 16050, 47987, 146191, 2518028, 7744270, 16819386 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 LINKS EXAMPLE log 2 = 0.693147180559945309417232121458... For example, a(2)=9 because the 9th digit of log 2 after decimal point is 0 and this is the first occurrence of 0. a(3)=2 because 2nd decimal digit of log 2 is 9, a(4)=22 because 22nd decimal digit of log 2 is 2 and so on. CROSSREFS Cf. A098266 (for e recurrence), A097614 (for Pi recurrence).
