Anationwide fast food restaurant is considering adding an innovative new item to its menu. it introduces the item at a few carefully selected restaurants that most accurately represent its test market and carefully evaluate consumers' reaction to it. which stage of the product development process does this best represent

This best represents the test marketing stage. During this stage, a new product is released on a small scale to a small market. Changes are made and if it is successful in the small market, then it is introduced on a larger scale.  

Part A: Geometric Sequence

Part B:

Part C: a₈ = 512

Step-by-step explanation:

When we find the common ratio between the y-values (x-values are n inputs), we should see that we get r = 2. That means we have a geometric sequence.

Because we have a geometric sequence, our recursive formula is: . Simply plug in our known variables:

Now we need to find what y is when x = 8, so (I used explicit formula):

a₈ = 512
