**Abstract**:
In the present investigation, we obtain some sufficient conditions involving L(a+1,c)f(z)/L(a,c)f(z) and L(a+2,c)f(z)/L(a+1,c)f(z)for
certain analytic function f(z) defined on the open unit disk in the complex plane to satisfy the subordination L(a+1,c)f(z)/L(a,c)f(z) < q(z),
where L(a,c) is the familiar Carlson-Shaffer linear operator.
