Summary: Let $K$ be a nonempty closed convex subset of a Banach space $E$ and $T : K \to K$ be a generalized Lipschitz pseudocontractive mapping. For any fixed Lipschitz strong pseudocontractive mapping $f : K \to K$, let the sequence $\{x_n\}$ be given by $x_1 \in K$, $x_{n+1}=(1-\alpha_n-\beta_n)x_n+\alpha_nf(x_n)+\beta_nTx_n$. It is shown, under appropriate conditions on the sequences of real numbers $\{\alpha_n\}$ and $\{\beta_n\}$, that $\{x_n\}$ strongly converges to some fixed point $x^*$ of $T$ whenever $\{z\in K: \mu_n \|x_n - z\|^2=\inf_{y \in K}\mu_n\|x_n-y\|^2\}\cap F(T)\neq \emptyset$.
