Answer
The next three terms are $-\frac{3}{5},-\frac{3}{25},-\frac{3}{125}$.
The points appear to lie on an exponential curve.
The graph is shown below.
Work Step by Step
The given sequence is
$-375,-75,-15,-3,...$
Use table to organize the terms.
Each term is divided by $5$ to the previous term. So, the common ratio is $5$.
Divide a term by $5$ to find the next term.
Plot the ordered pairs $(n,a_n)$.
The complete table is shown below.
