Let P(k) be the largest prime factor of the positive integer k. In this paper, we prove that the series ∑n≥1 (log n)α /{P(2 n-1) is convergent for each constant <1/2, which gives a more precise form of a result of C. L.Stewart [On divisors of Fermat, Fibonacci, Lucas and Lehmer numbers, Proc. London Math. Soc. 35(3) (1977), 425-447].
