 A073564 Number of Fibonacci numbers F(k), k <= 10^n, whose initial digit is 8. 0
 0, 1, 7, 53, 513, 5117, 51151, 511531, 5115248 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,3 LINKS FORMULA Limit as n -> inf. a(n)/10^n = log_10(9/8). EXAMPLE a(2)=7 because there are 7 Fibonacci numbers F(k), k <= 10^2 whose initial digit is 8, namely: k F(k) 6 8 11 89 30 832040 54 86267571272 73 806515533049393 78 8944394323791464 97 83621143489848422977 MATHEMATICA Table[Count[Fibonacci[Range[10^n]], _?(IntegerDigits[#][[1]]==8&)], {n, 0, 5}] (* Harvey P.
