Scan the sequence for odd digits (1, 5, 7, 9) and check if the digit immediately before and after them are both even (2, 4, 6, 8).
Scan the sequence for odd digits (1, 5, 7, 9) and check if the digit immediately before and after them are both even (2, 4, 6, 8).
Analyze the Sequence
List the full sequence: 9, 1, 7, 5, 1, 1, 4, 7, 2, 1, 9, 5, 4, 8, 5, 6, 6, 8, 7, 6, 8, 1, 5, 7, 6, 2, 8.
Identify Patterns
Look for triplets (Even, Odd, Even). Scanning: (4, 7, 2) is a match. Next, (8, 5, 6) is a match. Next, (6, 7, 6) is a match. (Note: other odd numbers like 1, 5, 9 either have at least one odd neighbor or are at the edge).
Verification
Total triplets found: (4, 7, 2), (8, 5, 6), and (6, 7, 6). The count is 3.
B: 5 is incorrect as there are not 5 such occurrences. C: 2 is incorrect as the count is exactly 3. D: 4 is incorrect as it overestimates the count of valid triplets.
A is correct because there are exactly 3 instances (4-7-2, 8-5-6, and 6-7-6) where an odd number is flanked by two even numbers.
In alphanumeric series questions, always write the series clearly on your rough sheet and use a pencil to underline or circle the required triplets to avoid skipping or double-counting.
