I've vastly rewritten the advice, and given the variables sensible names.

It would be good to have another version of this question where you fill in the table first.

I don't think this question is worth saving. I've split part d, about finding a given term, into a separate question.

Ideally, there'd be a question combining parts a and b, asking you to sort a few sequences into linear, quadratic, geometric, or other. 

I don't think there's any point in the parts which ask you to give the next three terms of the triangle, square, and cube numbers.
