Thread: [SOLVED] Nth Term

Given this sequence:
2,4,8,16,32

It should be so blindingly clear as I realise what's going on but I've tried different methods and so far I don't know how to solve it.

I have many questions based on the same lines so workings would be extremely helpful please

What methods have you tried? You've checked for arithmetic and geometric sequences, you've checked for powers,.... What else? And what were your results for each?

Please be complete. Thank you!
