Try looking at a few more terms in the sequence.
Look for a pattern between the terms of the sequence when n is odd, and when n is even.

I swear I answered this very question for you a week or two ago :smile:

I'd suggest organising your notes so when you've solved a problem under "sequences and series" you file it under that topic, then when you come to a similar (or the same problem) again, you can refer back to the hints you had previously. This will help to reinforce your knowledge and stop you forgetting stuff like this :smile:

You need to stay positive and focus on the questions where you think you can do well. But there do seem to be a lot of gaps in your basic knowledge from the questions you have posted!
