This paper addresses the solution of a differential-difference type equation having an interior layer behaviour. A difference scheme is suggested to solve this equation using a non-standard finite difference method. Finite differences are derived from the first and second order derivatives. https://www.diegojavierfares.com/mega-price-21-Ladder-4-Tier-Wooden-Cupcake-Holder-Dessert-Display-Stand-Whitewashed-flash-save/
