Table of n, a(n) for n=0..14.

Index entries for linear recurrences with constant coefficients, signature (101,-100).

Formula

a(n) = (89+10^(1+2*n))/99. a(n) = 101*a(n-1)-100*a(n-2). G.f.: -(90*x-1) / ((x-1)*(100*x-1)). - Colin Barker, Sep 02 2013

Example

A007583(2) = 11, which becomes 1011 when written in binary.
