In this note, we define the generalized Fibonacci-Narayana sequence {G n (a, b, c)} n∈N. After that, we derive some relations between these sequences, and permanents and determinants of one type of upper Hessenberg matrix. with initial conditions G 0 (a, b, c) = 0, G i (a, b, c) = 1, for i = 1, 2,. .. , c − 1. The constants a and b are nonzero real numbers. We call this sequence generalized Fibonacci-Narayana sequence. Note that, if a = b = 1 and c = 2, the Fibonacci sequence is obtained, and if a = 1 = b and c = 3, the Narayana sequence is obtained [1, 12]. Other particular cases of the sequence {G n (a, b, c)} n∈N are • If a = b = 1, the generalized Fibonacci sequence is obtained [2]. G n = G n−1 + G n−c. • If c = 2, the generalized Fibonacci sequence is obtained. G n = aG n−1 + bG n−2. • If a = k, b = 1 and c = 2, the k-Fibonacci sequence is obtained [10]. F k,n = kF k,n−1 + F k,n−2 .
