WebbAnswers and Replies. We may. change the index of summation from r to s=r+k. . Then because r starts from m, s should start from m+k and because r ends at n, s should end at n+k. This means that we changed our summation to . But you should note that this sum doesn’t depend on s as the first sum didn’t depend on r.
