We obtain a pointwise inequality valid for all submanifolds M n of all real space forms N n + 2 ( c ) with n 2 and with codimension two, relating its main scalar invariants, namely, its scalar curvature from the intrinsic geometry of M n , and its squared mean curvature and its scalar normal curvature from the extrinsic geometry of M n in N m ( c ) .
