In this paper, we prove a common ﬁxed point theorem for a sequence of mappings in cone metric spaces. This result oﬀers a generalization of Huang and Zhang’ theorem in . An example to support our result is presented.

The study of ﬁxed points of functions satisfying certain contractive conditions has been at the center of vigorous research activity, for example see [1-5] and it has a wide range of applications in diﬀerent areas such as nonlinear and adaptive control systems, parameterize estimation problems, fractal image decoding, computing magnetostatic ﬁelds in a nonlinear medium, and convergence of recurrent networks, see [6-10]. Recently, Huang and Zhang  have replaced the real numbers by ordering Banach space and deﬁne cone metric space. They have proved some ﬁxed point theorems of contractive mappings on cone metric spaces. The study of ﬁxed point theorems in such spaces is followed by some other mathematicians, see [12-15].
