A common interest in constant. It's $25 per year. Initial deposit is $500. After 10 years the amount of money in the account was $750. Using the arithmetic sequence which is tn= a+(n-1)d. Can you find how much money is in the account after 20 years?

It's $25 per year.
$\displaystyle d=+25$
Initial deposit is $500.
$\displaystyle a$ is greater than or equal to 500.
After 10 years the amount of money in the account was $750.
$\displaystyle T_n=a+(n-1)d$
$\displaystyle T_{10}=a+(10-1)d$
$\displaystyle a=$?
After 20 years.
$\displaystyle T_{20}=$?
