Question

find a pattern for the sequence below. use the pattern to find the next three terms. 24, 21, 18, 15, 12, ...

Explanation:

Step1: Identify the pattern

The common - difference between consecutive terms is \(21 - 24=- 3\), \(18 - 21=-3\), \(15 - 18=-3\), \(12 - 15=-3\). The pattern is that each term is 3 less than the previous term.

Step2: Find the next term

\(12-3 = 9\)

Step3: Find the second - next term

\(9-3 = 6\)

Step4: Find the third - next term

\(6-3 = 3\)
