Let R be a noncommutative prime ring and I a nonzero left ideal of R. Let g be a generalized derivation of R such that [g(r(k)), r(k)](n) = 0 for all r is an element of I, where k, n are fixed positive integers. Then there exists c is an element of U, the left Utumi quotient ring of R, such that g(x) = xc and I(c-alpha) = 0 for a suitable alpha is an element of C. In particular we have that g(x) = alpha x, for all x is an element of I.
