Question 742937: Write the first five terms of the sequence. Determine whether or not the sequence is arithmetic. If it is, find the common difference. (Assume n begins with 1.)
My teacher does more simplified versions of these problems so when we are given ones such as these I get confused as to how to go about them. Some explanations would be greatly appreciated as well as a quick answer to this. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A(n)=3+2(-1)^n
----
a(1) = 3+2*-1 = 1
a(2) = 3+2*1 = 5
a(3) = 3+2*-1 = 1
a(4) = 3+2*1 = 5
a(5) = 3+2*-1 = 1
======================
Not an arithmetic sequence.
