The convergence of the sequence $x_{n+1}=Ax_n+b$ to $(l-A)^{-1}b$ (where $x_n, b$ are vectors in Banach space, $A$ is a bounded linear operator with bounded $(l-A)^{-1}$) can be accelerated by constructing certain linear combinations of several ordinary successive approximations. A sufficient condition is that the spectrum of $A$ decompose into a finite set and a subset of a sufficiently small neighborhood of zero (e. g., $A$ is compact).
