A researcher determined the amount of ducks that were in a pond over a four-year time span. The results are shown in the table below. Year Ducks
1 64
2 78
3 92
4 106

Select an equation that best models the amount of ducks (d) that will be in the pond during the nth year.

d=64(1.22)^n−1

d=14n+50

d=14n+64

d=50(1.14)^n−1
