Question Analysis:
The question asks us to determine the number of odd numbers in the sequence that are immediately preceded and followed by an even number. We need to analyze the given sequence and identify the odd numbers that meet this condition.
Solution:
To solve this problem, we need to examine each number in the sequence and check if it is odd, and if so, whether it is immediately preceded and followed by an even number. Let's analyze the given sequence step by step:
Step 1:
Identify the odd numbers in the sequence:
- 5, 1, 7, 3, 5, 9, 7, 3, 1, 5, 3, 7
Step 2:
Check if each odd number is immediately preceded and followed by an even number:
- 5 is immediately preceded by 4 and followed by 3 (not even)
- 1 is immediately preceded by 5 and followed by 4 (even)
- 7 is immediately preceded by 4 and followed by 3 (not even)
- 3 is immediately preceded by 7 and followed by 2 (even)
- 5 is immediately preceded by 2 and followed by 6 (even)
- 9 is immediately preceded by 8 and followed by 6 (even)
- 7 is immediately preceded by 6 and followed by 3 (not even)
- 3 is immediately preceded by 7 and followed by 2 (even)
- 1 is immediately preceded by 3 and followed by 5 (not even)
- 5 is immediately preceded by 1 and followed by 6 (even)
- 3 is immediately preceded by 5 and followed by 2 (even)
- 7 is immediately preceded by 3 and followed by 4 (even)
Step 3:
Count the number of odd numbers that meet the condition:
- We have identified 4 odd numbers (1, 3, 5, 7) that are immediately preceded and followed by an even number.
Therefore, the correct answer is option 'A' (4).
