I'm doing a maths investigation and i have a sequence which goes:-


Our teacher told us we have to find a rule by looking at the differences of the terms until we find a constant. The first differences are:-


The differences of these are:- ......

Please could you tell me how to work it out so that I could work out the rules of similar sequences.
