Determine whether the sequence converges or diverges. if it converges, give the limit.

108, -18, 3, negative one divided by two,

Well, basically the way I decided to approach the problem was to first find the pattern between the numbers. Its not obvious between 108 and -18, but the pattern is the previous number divided by -6. From there, I believe you should be able to find whether or not it converges or diverges if you know the material (which you should xD)
