To determine the rule for generating the next term in the sequence 23, 19.5, 16, 12.5, we can look at the difference between each pair of consecutive terms:
- From 23 to 19.5, the difference is 19.5 - 23 = -3.5.
- From 19.5 to 16, the difference is 16 - 19.5 = -3.5.
- From 16 to 12.5, the difference is 12.5 - 16 = -3.5.
Since the difference between consecutive terms is consistently -3.5, we can conclude that we are adding the common difference of -3.5 to generate the next term.
Therefore, the correct statement is:
**Add the common difference of -3.5.**
- From 23 to 19.5, the difference is 19.5 - 23 = -3.5.
- From 19.5 to 16, the difference is 16 - 19.5 = -3.5.
- From 16 to 12.5, the difference is 12.5 - 16 = -3.5.
Since the difference between consecutive terms is consistently -3.5, we can conclude that we are adding the common difference of -3.5 to generate the next term.
Therefore, the correct statement is:
**Add the common difference of -3.5.**
