Sequence and Series Problem
Hey, everyone. I have a problem that I can't solve. The problem says:

"A sum of \$97 was deposited in a bank on January 1. A sum of \$31 is deposited in the bank on the 18th day of each month. Suppose the pattern continues. How much will be in the bank on August 1st?"

Any help would be greatly appreciated. Thank you.

the amount of money in the bank is 97 + 31n, where n is the number of deposits made, which tells you the number of months. just count off how many months it takes to get to Aug 1st, use that as n and you can find how much money you have. of course you start counting on the 18th day of the month. this perhaps includes January, the question seems vague on that
