Your uncle loaned you some money and did not charge interest. The amount you owe him at the end of each of the first 5 months is $937.50, $875.00, $760.00, and $687.00. If the pattern continues, how much will you still owe him at the end of one year?

937.5 - 875 = 62.50

875-760 = 115
760 - 687 = 73

I see no apparent "pattern"
