In 1999, the Peregrine falcon was finally removed from the endangered species list in the United States. It was estimated in 2013, that there were currently 2,800 breeding pairs (5600 birds) in Canada, Mexico and the US. If a population annual growth rate of 2.4% could be maintained, which equation could be used to predict the population pairs of Peregrine falcons n years after 2013?

Dana began an exercise program using a FitBit to measure her distance walked on her treadmill, in miles, per week. The following table shows her progress over three weeks.
Week

on treadmill
(miles) 
9 
11.7 
15.21 
If she continues to progress in this manner, which of the listed statements could model the number of miles Dana walks on her treadmill, a_{n}, in terms of n, the number of weeks?
