Which answer describes the type of sequence? 200, 40, 8, 1.6, -geometric -arithmetic -neither arithmetic nor geometric

Option 1  the given sequence is a geometric.

Step-by-step explanation:

We have been given with the series

Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d

  here

         here

We can see the difference is not same

Hence, the given sequence is not arithmetic sequence.

Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r

  here

         here

            here

We can see the ratio is  same.

Hence, given sequence is geometric

Therefore, Option 1 is correct given sequence is geometric.
