Question

Dalton is saving up money to buy a car. He deposits $10 in his savings account the 1st month. Each month after that, he deposits $5 more than the amount he deposited the previous month. Thus, Dalton's deposit is $15 the 2nd month, $20 the 3rd month, and so on. He makes his final deposit of $95 the 18th month . How much money does Dalton have in his account after these 18 deposits ?

Answer 1

$945, there’s probably a faster way but i just took every increment of 5 from 10 to 95 and that was the answer, hope this helps!
