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?

By doubling each day

Step-by-step 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).

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

47 - 90 = 43

43 - 180 = x

x = 137
