8-8.

Review problem 7-108. Write the equation for the following sequences in “first term” form.

1. $500,2000,3500,\dots$

Find the first term. How much do these values increase going from left to right?

$t(n) = 500 + 1500(n − 1)$

1. $30,150,750,3750,\dots$

Notice that the numbers in this sequence do not increase by the same amount each time.

Each term is the previous term multiplied by $5$. Your answer will include an exponent.
