The series starts with n as 2n, I haven't done anything like this before.

I don't understand what to do for these.

Do you mean Exercise A questiuon 10, if so the series is from r=1 to r=2n so I don't understand what you are saying about it starting with n as 2n.

Generally in the excerise book and in past papers these specific questions are from r=n to r=1.

My question is does something else need to be done when it is from r=2n to r=n.

the sum from r=n to r=2n is the sum from r=1 to r=2n minus the sum from r=1 to r=n-1.
