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.

A1+B1, A+d1+B1+d2, ....

AxB means several things, but I assume you are working as a orthogonal tensor, which means that each term (like terms) are multliplied:

AB, Ar1*Br2, A(r1)^2 B(r2)^2, ...AB (r1*r2)^n, .....
