In the given paper we first introduce $\bar{N}_{\Delta^{-}}^{q}$ summabledifference sequence spaces and prove some properties of these spaces. We thenobtain the necessary and sufficient conditions for infinite matrices $A$ to mapthese sequence spaces on the spaces $c_0, c$ and $\ell_\infty$, the Hausdorffmeasure of noncompactness is then used to obtain the necessary and sufficientconditions for the compactness of the linear operators defined on these spaces.
