To determine the rule for generating the next term in the sequence 23, 19.5, 16, 12.5, we first need to identify the differences between consecutive terms:

23 to 19.5: 19.5 - 23 = -3.5
19.5 to 16: 16 - 19.5 = -3.5
16 to 12.5: 12.5 - 16 = -3.5

The common difference between the terms is -3.5.

Therefore, the correct statement is:

Add the common difference of -3.5.
