You and a group of friends take turns planting 2 trees each at a campsite. After the first person plants 2 trees, there are 12 trees at the campsite. A. Write an equation for the nth term of the arithmetic sequence. Let n represent the position in the sequence and let an represent the number of trees. C. After 8 more people plant trees, how many trees are at the campsite?

The equation for the nth term will be;

An = 10 + 2n

After the 9th planter ( 8 more than the initial one); number of trees will be 28

Step-by-step explanation:

After the first person plant two trees, there were 12 trees at the plant sites

What this mean is that initially, they were 12-2 = 10 trees at the plant site

The nth term of the sequence which represents the number of trees given the number of persons that have planted will be;

An = 10 + 2n

Now, after 8 more people planted, since we had one that already planted, the total number of planters is now 9 planters

So using the equation, n will be 9

So ; A9 = 10 + 2(9)

A9 = 10 + 18

A9 = 28

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
