Application of Geometric Calculus in Numerical Analysis and Difference   Sequence Spaces
  The main purpose of this paper is to introduce the geometric difference sequence space   $l_\infty^{G} (\Delta_G)$ and prove that $l_\infty^{G} ({\Delta}_{G})$ is a Banach space with respect to the norm $\left\|.\right\|^G_{{\Delta}_G}.$ Also we compute the $\alpha$-dual, $\beta$-dual and $\gamma$-dual spaces. Finally we obtain the Geometric Newton-Gregory interpolation formulae.
