Final answer:
The given sequence 9, 12, 15, 18, 21, 24 is a linear representation where each term is obtained by adding a constant value of 3 to the previous term.
Step-by-step explanation:
The given sequence 9, 12, 15, 18, 21, 24 can be described as a linear representation. In a linear representation, each term is obtained by adding a constant value to the previous term. In this case, the constant value is 3. So, to find the next term, you add 3 to the previous term. For example, 24 + 3 = 27, so the next term would be 27.
