c) the common ratio is -2.0
d) the common ratio is -0.5

Answer 1

The successive terms in the sequence have a common difference that is always positive and steadily decreasing.

Step-by-step explanation:

The relationship between the successive terms in the sequence 2.4, -4.8, 9.6, -19.2 is best described by option a) the common difference is always positive, steadily decreasing.

1. The first term is 2.4.
2. To find the common difference, we subtract each term from its previous term.
3. Since the common difference is steadily decreasing, we can see that it is a positive value.
