Approximate fixed point property problem for Mann iteration sequence of a nonexpansive mapping has been resolved on a Banach space independent of uniform (strict) convexity by Ishikawa [{\it Fixed points and iteration of a nonexpansive mapping in a Banach space}, Proc. Amer. Math. Soc. {\bf 59} (1976), 65--71]. In this paper, we solve this problem for a class of mappings wider than the class of asymptotically nonexpansive mappings on an arbitrary normed space. Our results generalize and extend several known results.
Keywords: nearly asymptotically nonexpansive mapping, asymptotically nonexpansive mapping, Mann iteration, nearly uniform $k$-contraction mapping, Opial condition
