Solution
Solution Steps
To identify the pattern, observe the differences between consecutive numbers. Once the pattern is identified, apply it to find the next three numbers in the sequence.
Step 1: Identify the Pattern
To identify the pattern, we calculate the differences between consecutive numbers in the sequence:
\[
97 - 89 = 8
\]
\[
89 - 81 = 8
\]
\[
81 - 73 = 8
\]
The differences are consistent, indicating that the sequence decreases by 8 each time.
Step 2: Apply the Pattern
Using the identified pattern, we can find the next three numbers in the sequence by continuing to subtract 8 from the last number:
\[
73 - 8 = 65
\]
\[
65 - 8 = 57
\]
\[
57 - 8 = 49
\]
