In this work, we apply the Adomian Decomposition Method(ADM) for solving first order impulsive differential equations x (t) =x, t k,t > 0, x = x, t = k, (0 ) = , 0 x x where 0,, x0 R,1 0,k N are investigated. We compare this method with others numerical methods such as -method, Runge-kutta method for solving impulsive differential equations.
