This article [1] has been retracted by Professor Ravi P Agarwal, Editor-in-Chief of Advances in Difference Equations.

Following publication of this article, it was brought to the attention of the editorial and publishing staff that this article has substantial overlap with two articles by Hadizadeh, Ghoreishi, and Pishbin, published in 2011 in Applied Numerical Mathematics [2] and in 2013 in Journal of Computational and Applied Mathematics [3].

This is a violation of publication ethics which, in accordance with the Committee on Publication Ethics guidelines, warrants a retraction of the article and a notice to this effect to be published in the journal.
