Question

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.
A an = 51 + 6(n − 1)
B an = 9 + 6(n − 1)
C an = 51 + 7(n − 1)
D an = 9 + 7(n− 1)

Answer 1

Answer:

D an = 9 + 7(n-1)

Step-by-step explanation:

In the question, Max has 9 logs in the first load. But, after the seventh load he has a total of 51 logs. So the n would be your logs in the stack, which is 51. And since there is a total of 51 logs after the seventh load. It would be 9 plus 7 in parenthesis of  51 minus one, which is 50. So 50 times 7 comes down to 350 plus nine which comes down to a total of 359.
