Alright so my teacher decides to give us this problem with minimal instruction, and my book is awful.
Fiven the following sequence 8,14,20,26
Find the nth term
Find sn(phoenetically sounds S sub n )
Prove your formula works for all n

Instead of writing out answers i will nearly work out by giving hints
Find the nth term:
Mathstud28 already gave you the answer (assuming n starts from 0)
If you know arithmetic progressions, the series you have is an A.P with first term '8' and common difference '6'.
So
Find sn(phoenetically sounds S sub n )
