David A. Corneth, Table of n, a(n) for n = 1..10000

Index entries for linear recurrences with constant coefficients, signature (1).

FORMULA

a(n) = 1000 for n >= 1001.

a(n) = 0 <=> n in { A018767 }.

a(n) = 1 <=> n > 1 and n in { A018766 }.

EXAMPLE

a(98) = 1000 mod 98 = 20 as 1000 = 98 * 10 + 20. - David A. Corneth, Mar 07 2019
