What is the common difference between ratio between successive terms in the sequence 1.5, 1.2, 0.96, 0.768

First, we should see if there are any common differences. We do this by subtracting each term from its previous:

1.5 - 1.2 = 0.3

1.2 - 0.96 = 0.24

Already, we can tell that there is no common difference.

Let's look at common ratio:

1.2/1.5 = 0.8

0.96/1.2 = 0.8

0.768/0.96 = 0.8

Therefore, there is a common ratio and it is 0.8.

Answer is D: 0.8

Step-by-step explanation:

r = 1.2 / 1.5 = 0.8
