The paper investigates a second order difference equation of the Emden-Fowler type Lambda(2)u(k) +/- k(alpha)u(m)(k) = 0, where k is the independent variable taking values k = k(0), k(0) + 1,... with k(0) a fixed integer, u: {k(0), k(0) + 1, ...} -> R is the dependent variable and.2u(k) is its second-order forward difference. New conditions with respect to parameters m is an element of R, m not equal 1 and alpha is an element of R are found such that the equation admits a solution asymptotically represented by a power function asymptotically equivalent with the exact solution of second-order differential Emden-Fowler equation y ''(x) +/- x(alpha)y(m)(x) = 0.
