Missing Number Fe00C5

1. The problem presents a series of date ranges with associated sequences of numbers, ending with an incomplete sequence containing an asterisk (**). The task is to determine the missing number represented by **. 2. To solve this, we need to analyze the patterns in the sequences of numbers for each date range and identify any relationships or rules that can help predict the missing value. 3. Let's list the sequences for each date range: - 20/07/2026 to 25/07/2026: 31, 31, 78, 00, 04, 74 - 25/07/2026 to 01/08/2026: 26, 26, 45, 28, 23, 32 - 03/08/2026 to 08/08/2026: 99, 65, 66, 89, 59, 67 - 10/08/2026 to 15/08/2026: 26, 81, 38, 37, 26, ** 4. We focus on the sequence with the missing number: 26, 81, 38, 37, 26, **. 5. Observing the sequences, the first and fifth numbers in this sequence are both 26, suggesting a possible pattern or symmetry. 6. Let's check if the last number might be related to the first or other numbers. One approach is to check if the last number equals the second number (81) or the fourth number (37), or if it follows a pattern such as the sum or difference of certain numbers. 7. Another approach is to check if the sequences follow a pattern in their sums or differences: - Sum of first five numbers in the sequence with missing number: $$26 + 81 + 38 + 37 + 26 = 208$$ 8. Looking at other sequences, sums vary widely, so sum alone may not help. 9. Alternatively, check if the last number equals the average of some numbers: - Average of first five numbers: $$\frac{208}{5} = 41.6$$ 10. Since 41.6 is not an integer and the sequences contain integers, this may not be the pattern. 11. Another observation is that the first and fifth numbers are equal (26), so the last number might be equal to the second number (81) or the fourth number (37) to maintain symmetry. 12. Given no further information or clear pattern, the best assumption is that the missing number is 81, matching the second number to maintain symmetry. 13. Therefore, the missing number represented by ** is 81. Final answer: **81**
