Answer:
and $475 deposited into the account on her birthdays by her 18th birthday.
Step-by-step explanation:
It is given that, on Gabriela’s first birthday, her parents gave her a $50 savings account.
Initial term : ![a_1=50](https://tex.z-dn.net/?f=a_1%3D50)
On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year.
Common difference : ![d=25](https://tex.z-dn.net/?f=d%3D25)
It forms an AP: 50,75,100,...
nth term of an AP is
![a_n=a_1+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da_1%2B%28n-1%29d)
Substitute
and
in the above formula.
![a_n=50+(n-1)25](https://tex.z-dn.net/?f=a_n%3D50%2B%28n-1%2925)
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.
![a_{18}=50+(18-1)25](https://tex.z-dn.net/?f=a_%7B18%7D%3D50%2B%2818-1%2925)
![a_{18}=50+(17)25](https://tex.z-dn.net/?f=a_%7B18%7D%3D50%2B%2817%2925)
![a_{18}=50+425](https://tex.z-dn.net/?f=a_%7B18%7D%3D50%2B425)
![a_{18}=475](https://tex.z-dn.net/?f=a_%7B18%7D%3D475)
Therefore, $475 deposited into the account on her birthdays by her 18th birthday.
