You have made a small mistake @25:52. Whenever one writes in Sigma Notation (or Summation Notation), it is crucial to keep the variables the same (you are supposed to use one variable in your example, unless you want to contradict the work that you have shown), unless of course the problem calls for the use of more than one variable. The index variable that you used in this lesson does not match the variable in the formula. Later, when you go about solving this problem, you do are not consistent
