A level further maths help

Hi, I did a mock a few weeks ago and got this question wrong. I've corrected it best I can, but using the mark scheme am unsure why n=3 isn't a valid answer. https://flic.kr/s/aHBqjAF9B9

Your sum doesnt really make sense with n=3 as it starts at 5, but it would help to see the full question.
