nth term of an AP is

Substitute
and
in the above formula.

It represents the amount deposited into the account after n birthdays.
We need to find the amount by her 18th birthday.
Put n=18 in the above equation.




Therefore, $475 deposited into the account on her birthdays by her 18th birthday.

Answer:
3
Step-by-step explanation:
(4^4-2)*1/2+20 OVER 3^4-(2^4)*2
256-1*1 +20/2 OVER 3^4-(2^4)*2
254+20/2 OVER 3^4-2^4*2
127+10 OVER 3^4-2^4*2
147 OVER 3^4-2^4*2
147 OVER 81-2^4*2
147 OVER 81-16*2
147 OVER 81-32
147/49
3 is the answer
We know that
• It takes 8 hours to travel a certain distance at 36 miles per hour.
,
• At 60 miles per hour, how long would it take?
We solve this problem using the rule of three, or proportions. The image below shows the given relations.
We form the proportion. We have to write down 60 as numerator because it has an inverse relationship, that is, the more speed the least time needed.

<h2>Therefore, it would take 4.8 hours to travel the same distance at 60 miles per hour.</h2>
