Big trouble with A049602

[Paul D. Hanna]

Hello Thomas, 
       Perhaps this is the formula for a(n) that you had?
This is what is NOW in A049602:
(1)  Floor((lucas(2n)-lucas(n))*sqrt(5)/10+(n%2)?fibonacci(n):1).
 
Here is my PARI code that generates sequece A049602:
   
(2) 
a(n)=floor((lucas(2*n)-lucas(n))/(5+sqrt(5))+(n%2)*fibonacci(n)+(1-n%2))
 
where:
 
(3)  lucas(n)=fibonacci(n+3)-fibonacci(n-1)
  
Paul
