Error still present as above - should be 2n^2, not 4n^2

Sir, on slide 9, sequence 3 has the answer beginning with 4n^2, I believe this should be 2n^2 as it is necessary to halve the second difference. It is not a major error, however, I thought I should inform you. Nevertheless, I find the inclusion of these slides extremely helpful as I can return to topics which I am confused about.
