Homework Help: Sequences

Posted by Nelson on Sunday, September 30, 2007 at 2:30pm.

A = {a1, a1 + d1, a1 + 2d1, }, B = {a2, a2 + d2, a2 +2d2, }. Investigate whether A + B and
A x B are arithmetic or geometric sequences. If an arithmetic sequence is identified, state its common difference. If a geometric sequence is identified, state its common ratio. (the numbers are subscripts)

I can't seem to model this one.
I'd appreciate some input.
