The first is successive differences, that is you take the difference of each term from the previous term. Here is an example. Try it with your sequence. A second technique is to take successive quotients, that is take the quotient of each term by the previous term. Try it. Penny
A very important 'big idea' is that there are several possible sequences, in all of these cases. There are reasons why ATT Research host such a site  and that would be interesting to investigate. Given this came from a school exercise, I suspect that the first match is what the book/teacher anticipated. Walter Whiteley
