An arithmetic sequence is given below.
12,16,20,24
wright an explicit formal for the nth term an.
an=?

Step-by-step explanation:

The nth term of an arithmetic sequence is given by the formula:

Where

a is the first term

d is the common difference

a is given as 12

To find d, we subtract any term from the term after it. So

d = 16 - 12 = 4

Now, the explicit formula for nth term is:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
