What is the recursive rule for the sequence 2, -1, 1/2 , -1/4

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:

yes

step-by-step explanation:

yes

what? that isnt a question
