Answer 1

To determine the rule for generating the next term in the sequence 23, 19.5, 16, 12.5, we can look at the differences between consecutive terms.

1. From 23 to 19.5: 19.5 - 23 = -3.5
2. From 19.5 to 16: 16 - 19.5 = -3.5
3. From 16 to 12.5: 12.5 - 16 = -3.5

Each term is decreasing by 3.5, which indicates that the rule for generating the next term is to add the common difference of -3.5.

So, the correct response is:

Add the common difference of −3.5.
