A ring R is called a right Ikeda-Nakayama (for short IN-ring) if the left annihilator of the intersection of any two right ideals is the sum of the left annihilators, that is, if (IJ)=(I)+(J) for all right ideals I and J of R. R is called Armendariz ring if whenever polynomials f(x)=a0+a1x++amxm, g(x)=b0+b1x++bnxnR[x] satisfy f(x)g(x)=0, then aibj=0 for each i,j. In this paper, we show that if R[x] is a right IN-ring, then R is a right IN-ring in case R is an Armendariz ring.
