O článku:
Let $k≥ 1$ and denote $(Fk,n)n≥ 0$, the $k$-Fibonacci sequence whose terms satisfy the recurrence relation $Fk,n=kFk,n-1+Fk,n-2$, with initial con di tions $Fk,0=0$ and $Fk,1=1$. In the same way, the $k$-Lucas sequence $(Lk,n)n≥ 0$ is defined by satisfying the same recurrence relation with initial values $Lk,0=2$ and $Lk,1=k$. These sequences were introduced by Falcon and Plaza, who showed many of their properties, too. In particular, they proved that $Fk,n+1+Fk,n-1=Lk,n$, for all $k≥ 1$ and $n≥ 0$. In this paper, we shall prove that if $k≥1$ and $Fk,n+1s+Fk,n-1s\in (Lk,m)m≥ 1$ for infinitely many positive integers $n$, then $s=1$.
