For the following geometric sequence, find the recursive formula.
{-80, 20, -5, }

Step-by-step explanation:

We can get geometric sequence dividing each term by -4

So we will have:

We can prove it putting the first value in this recursive equation:

x₁=-80

n = 1

If x₂ = 20, the next value will be:

I hope it helps you!

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.
