O Add the common ratio of -3.5.

O Multiply by the common ratio of -3.5.

O

Multiply by the common difference of -3.5.

Answer 1

Correct rule: add the common difference of -3.5 (equivalently, subtract 3.5).

Reason: 19.5−23 = 16−19.5 = 12.5−16 = −3.5, so each term is 3.5 less than the previous. The next term after 12.5 is 12.5 + (−3.5) = 9.0.
