Let $E$ be a real Banach space and
$T$ be a continuous $\Phi-$strongly accretive operator. By using a
new analytical method, it is proved that the convergence of Mann,
Ishikawa and three-step iterations are equivalent to the convergence
of multistep iteration. The results of this paper extend the results
of Rhoades and Soltuz in some aspects.
