    The main result of the paper is a convergence theorem for the iterative scheme \[ x_{n+1}=(1-\sigma) x_n + \sigma [T x_n-\delta G(T x_n)],\quad n\geq 0, \] used to approximate the unique solution of the variational inequality \[ VI(G,K): \left\langle G x^*,j_q(y-x^*)\right\rangle \geq 0\quad \forall y \in K. \] Here \(E\) is real \(q\)-uniformly smooth Banach space, \(T:E\rightarrow E\), \(G:E\rightarrow E\) are self-mappings, and \(j_q(.)\) denotes the generalized duality mapping.
