Understanding the Series
The series presented is: 81, 27, 9. To find the pattern, we need to analyze how each number relates to the next one in the sequence.
Identifying the Pattern
1. First Number: 81
- The first number is 81.
2. Second Number: 27
- To get from 81 to 27, we divide 81 by 3.
- Calculation: 81 ÷ 3 = 27
3. Third Number: 9
- To move from 27 to 9, we again divide by 3.
- Calculation: 27 ÷ 3 = 9
Conclusion: The Rule
- From the analysis, we see that each number is obtained by dividing the previous number by 3.
- Therefore, the pattern rule for the series is to divide by 3.
Why Option B is Correct
- Option B: Divide by 3 is indeed the correct answer as it accurately describes the relationship between the numbers in the series.
- Other options do not apply:
- Multiply by 3 would increase the numbers, which is not the case.
- Add 3 and Subtract 3 would not yield the numbers in the series.
In summary, the correct pattern rule is to divide by 3, confirming that option B is the right choice.
