Answer:


Step-by-step explanation:
The recursive rule is a term defined in terms of other terms in the sequence.
The is a geometric sequence because it has a common ratio.
The common ratio can be found by dividing a term by previous term.
For example, all of these are equal:



They are all equal to
.
So we are saying:

More formally:
.
Multiply both sides by
:

When doing recursive form, you need to state a term of the sequence (or more depending on the recursive form you have).
So the first term is 2.
So the full thing for the answer is:


Answer:
Step-by-step
explanation:

This cannot be factored because you can'y take a number out.
This is factoring. 
This is not factoring. 
Hope this helps. :)
$0.86. You either divide by 10 manually, or use the powers of 10.
