Question

I need to get this right to finish the lesson

Answer 1

For each job you complete, you get quadruple (4 times) the amount of pennies as the previous job. This is a geometric sequence, which looks like
`4^1, 4^2, 4^3, ...`! Therefore, the 9th job will give you
`4^9` pennies, or 262,144 pennies.
