Question

Jay on started off his penny collection with 1 penny. He then adds 5 pennies to his collection each day. How could you change the above scenario to make it a geometric series rather than an arithmetic series?

Answer 1

By doubling each day

Explanation:

Jay is increasing daily a fixed amount of pennies to his collection. That's an arithmetic series, because to obtain the next term you have to do an addition.

To get a geometric series or progression you have to find the next term through multiplication.

So, if he wants to convert his series into a geometric series, he'd have to double his contribution to his collection each day (as an example).
