A strong convergence theorem of the proposed iterative scheme to a common fixed point of a countable family of nonexpansive mappings and a solution of variational inequality of an inverse strongly monotone mapping are established. Moreover we apply our main result to obtain strong convergence theorems for a countable family of nonexpansive mappings and a strictly pseudocontractive mapping and a countable family of uniformly k-strictly pseudocontractive mappings and an inverse strongly monotone mapping. Our main results improve and extend the corresponding result obtained by Klin-eam and Suantai J Inequal Appl 520301 16 pp 2009 .

In this paper we always assume that a bounded linear operator A on H is strongly positive that is there is a constant Y 0 such that Ax x Y x 2 for all x e H. Recall that a mapping T of H into itself is .
