  We consider the Grothendieck polynomials appearing in the K-theory of
Grassmannians, which are analogs of Schur polynomials. This paper aims to
establish a version of the Murnaghan-Nakayama rule for Grothendieck polynomials
of the Grassmannian type. This rule allows us to express the product of a
Grothendieck polynomial with a power sum symmetric polynomial into a linear
combination of other Grothendieck polynomials.
