HELP fast please!!!!!Classify the sequence as arithmetic, geometric, or neither. If there is not enough information to classify the sequence, choose not enough information. (12+(-8)+16/3+(-32/9)+64/27) Then, determine if the series is convergent or divergent.

The sequence is geometric. The infinite series does converge.

Note how dividing any given term by the previous one leads to the same result
-8/12 = -2/3
(16/3) divided by -8 = -2/3
and so on...
So the common ratio is r = -2/3. This proves the sequence is geometric.

Since |r| < 1 is true, this means the infinite series converges to some fixed number.
