8-8.

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

500, 2000, 3500, …

30, 150, 750, 3750, …

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

*t*(*n*) = 500 + 1500(*n* − 1)

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.
