This study presents the differential transform method and its modification proposes a combination of the differential transform method, Tarig transformation and the Pade approximation. This combination may be used as a beneficial strategy to expand the domain of convergence of the approximation solutions. Moreover, the modified differential transform method will be used to solve linear and nonlinear delay differential equations, and this technique will be applied to models of delayed vector-borne diseases and delayed protein degradation.
