Aurora is planning to participate in an event at her schools field day that requires her to complete tasks at various stations in the fastest time possible. to prepare for the event, she is practicing and keeping track of her time to complete each station. The x-coordinate is the station number, and the y-coordinate is the time in minutes since the start of the race that she completed the task.

(1, 4), (2, 8), (3, 16), (4, 32)

Part A: Is this data modeling an arthmetic sequence or geometric sequence? Explain your answer.

Part B: Use the recursive formula to determine the tine she will complete station 5. Show your work.

Part C: Use an explicit formula to find the time she will complete the 8th station. Show your work. ​
