1001, 1000, 997, 992, 985, ?
Correct Answer
976
[Sequence Difference Extraction]: To decode the pattern, we must calculate the numerical gaps between consecutive terms in the series.[Step-by-Step Calculation]......
💡 Analysis & Explanation
[Sequence Difference Extraction]
To decode the pattern, we must calculate the numerical gaps between consecutive terms in the series.
[Step-by-Step Calculation]
1001 - 1000 = 1
1000 - 997 = 3
997 - 992 = 5
992 - 985 = 7
[Pattern Identification]
The subtracted values form an ascending sequence of consecutive odd numbers: 1, 3, 5, 7. Therefore, the next logical subtraction must be 9.
[Final Application]
Applying this rule to the last known number: 985 - 9 = 976.
Conclusion
The number that perfectly completes the series is 976.
