Question

PLZ HELP :(

The ordered pairs model an exponential function, where p is the function name and t is the input variable.

{(1, 80), (2, 240), (3, 720), (4, 2160)}

What is the function equation in sequence notation?

Enter your answer in the box.

pt=

Answer 1

Actually the answer is 80(3)^t-1

i put your answer and got it wrong!!!!X(

Step-by-step explanation: So for any future people needing help the answer is:

80(3)^t-1

hope I helped!!!

Answer 2

The ordered pairs are:
{(1, 80), (2, 240), (3, 720), (4, 2160)}

with
a_1 = 80
a_2 = 240
a_3 = 720
a_4 = 2160

The terms are in a geometric sequence with a common ratio of
240/80 = 720/240 = 2160/720 = 3

The equation is:
a_n = 80 * 3^(n - 1)
