The aim of this paper is to give linear independence results for the values of certain series. As an application, we derive arithmetical properties of the sums of reciprocals of Fibonacci and Lucas numbers associated with certain coprime sequences {n ℓ } ℓ≥1 . For example, the three numbersare linearly independent over Q( √ 5), where {Fn} and {Ln} are the Fibonacci and Lucas numbers, respectively.
