To prove our theorems, we make use of Mertens’ theorems on the … Nettetthe Lehmer sequences. 1. INTRODUCTION In [1], V. Drobot introduced the following theorem. It gave a set of sufficient conditions for a Fibonacci number of prime index to be composite. Theorem 1 (Drobot): Let p > 7 be a prime satisfying the following two conditions: 1. p ≡ 2 (mod 5) or p ≡ 4 (mod 5) 2. 2p − 1 is prime Then, F p is composite.
