write a rule for finding a term of each sequence when you know the previous term.


x/3,x/9,x/27...........[/b]

 

[Unco]

How do you think we could go from \(\displaystyle \mbox{\frac{x}{3}}\) to \(\displaystyle \mbox{\frac{x}{9}}\), and then from \(\displaystyle \mbox{\frac{x}{9}}\) to \(\displaystyle \mbox{\frac{x}{27}}\)?

. . . what would be multiply (or divide) by?

If you multiply one-third by three, you will not get one-ninth.

As for the "top number", there is no number; just a constant "x".
