 abstract={ We establish a Banach space version of a theorem of Suzuki \cite {Su}. More precisely we prove that if $X$ is a uniformly convex Banach space with a weakly continuous duality map (for example, $l^p$ for $1<p<\infty $), if $C$ is a closed convex subset of $X$, and if $\mathcal {F}=\bigl \{T(t):t\ge 0\bigr \}$ is a contraction semigroup on $C$ such that $\Fix (\mathcal {F})\not =\emptyset $, then under certain appropriate assumptions made on the sequences $\{\alpha _n\}$ and $\{t_n\}$ of the parameters, we show that the sequence $\{x_n\}$ implicitly defined by $$x_n=\alpha _n u+(1-\alpha _n)T(t_n)x_n$$ for all $n\ge 1$ converges strongly to a member of $\Fix (\mathcal {F})$. }
