What is the explicit formula for this sequence?
-7,-3, 1,
a. an = -7 + (n - )
b. an = 9+ (n - )
c. an = -7 + (n - 114
d. an= -4 + (n -

or

Step-by-step explanation:

-7,-3,1,5,... is a arithmetic sequence.

Arithmetic sequences have a common difference. That is, it is going up by 4 each time.

When you see arithmetic sequence, you should think linear equation.

The point-slope form of a line is .

m is the common difference, the slope.

Any they are using the point at x=1 in the point slope form.  So they are using (1,-7).

So let's put this into our point-slope form:

Subtract 7 on both sides:

So your answer is
