Answer

Answer:

exponential, because there is a relatively consistent multiplicative rate of change

Explanation:

Step1: Calculate additive rate of change

$180 - 200=- 20$, $163 - 180=-17$, $146 - 163=-17$, $131 - 146=-15$, $118 - 131=-13$, $107 - 118=-11$. Additive rate is not consistent.

Step2: Calculate multiplicative rate of change

$\frac{180}{200}=0.9$, $\frac{163}{180}\approx0.906$, $\frac{146}{163}\approx0.896$, $\frac{131}{146}\approx0.897$, $\frac{118}{131}\approx0.901$, $\frac{107}{118}\approx0.907$. There is a relatively consistent multiplicative rate of change, so it is exponential.
