Is the sequence Arithmetic: 37, 31, 25, 19

Yes, it is an Arithmetic Sequence

Step-by-step explanation:

Since the difference between any two consecutive terms is same (- 6). Hence, 37, 31, 25, 19 is an Arithmetic sequence.

To determine how many times larger is a 10-pound dog compared to a 5/8-pound hamster, we divide the mass of the dog by the mass of the hamster. This is as shown below,
               n = mass of the dog / mass of the hamster

Substituting the known value,
              n = 10 lb/ 5/8 lb
              n = 16

ANSWER: 16 times
