In this paper we introduce the difference sequence spaces c0(∆v), c(∆v), l∞(∆v), and bv(∆v). The properties of difference sequence spaces i.e. AK-Property, BK-Space, normality, Schauder basis and Ko¨the - Toeplitz duals are also the part of our studies. We extentded the work done by Kizmaz on the difference sequence spaces c0(∆),c(∆)andl∞(∆) and V. K. Bhardwaj and Sandeep Gupta on Cesaro summable difference sequence spaces C1(∆).

Difference Sequence Spaces, BK-space, Schauder basis, α−, β− and γ − duals and K¨othe - Toeplitz duals.
