In circle L with m \angle KLM= 54m∠KLM=54 and KL=12KL=12 units find area of sector KLM. Round to the nearest hundredth.

 In any arithmetic sequence, each term is equal to the previous term plus the common difference. 

 Thus, the second term is equal to the first term plus the common difference. In this sequence, the second term, 5, is 3 less than the first term, 8. 

 Therefore, the common difference is -3.
