Find the next four terms in the arithmetic sequence.
2 answers:
To find the arithmetic sequence, we can first find it's common difference by deducting the first term by the second term:
-7-(-15)
=-7+15
=8
Therefore the common difference is 8, and to find the remaining terms we can add 8 for the respective terms.
T(4) = 1+8 =9
Therefore the answer is c)9,17,25,33.
Hope it helps!
Answer: c) 9,17,25,33
Step-by-step explanation:
Use the equation 
Where "n" is the nth term,
is the first term, "d" is the common difference and "n" is a integer greater than zero.
Find the common diference "d":

Then we know that:

Since we need to find the next four terms and we know three terms then:

You’d have to try to get r on one side of the equation.
You can do that by subtracting 12 from both sides which would make it so
R = -9
