Max is stacking logs at his campground for firewood. After his first load of logs, he has 9 logs on the stack. After his seventh load of logs, he has 51 logs on the stack Use sequence notation to represent the arithmetic function
O an = 51 + 6(n-1)
O an = 9 + 6(n-1)
O an = 51 + 7(n-1)
an = 9 + 7(n-1)
