ANSWER
![\begin{gathered} a_n=ar^{n\text{ - 1}} \\ a_8\text{ = \$38.26} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a_n%3Dar%5E%7Bn%5Ctext%7B%20-%201%7D%7D%20%5C%5C%20a_8%5Ctext%7B%20%3D%20%5C%2438.26%7D%20%5Cend%7Bgathered%7D)
EXPLANATION
The problem represents a geometric progression.
The general form of a geometric sequence is:
![a_n=ar^{n\text{ - 1}}](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn%5Ctext%7B%20-%201%7D%7D)
where a = first term
r = common ratio
The first term from the table is the first price (for the first month). That is $80.00
To find the common ratio, we divide a term by its preceeding term.
Let us divide the price of the second month from the first.
We have:
![\begin{gathered} r\text{ = }\frac{72}{80} \\ r\text{ = 0.9} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20r%5Ctext%7B%20%3D%20%7D%5Cfrac%7B72%7D%7B80%7D%20%5C%5C%20r%5Ctext%7B%20%3D%200.9%7D%20%5Cend%7Bgathered%7D)
The price after the 8th month is the value of a(n) when n = 8
So, we have that:
Gareth has $2,000 to invest. Putting the money in a savings account at his local bank will earn him 2.2% annual interest.
Interest earned in local bank = 2000 * 22.2% = 2000 * 0.022 = 44
Putting the money in an online savings account will earn him 4.85% annual interest
Interest earned in online account = 2000 * 4.85% = 2000 * 0.0485 = 97
He will be charged $3 every time he makes an ATM withdrawal.
In online account, the interest is 97 . If he withdraws 18 times then
Total ATM fee is 18 * 3= 54 . so 97 - 54 = 43
43 is lower than 44 that is interest of local account.
Therefore, 18 ATM withdrawals make local savings account to be a better deal than the online savings account every year.
