Identifying the Wrong Number in the Series:
1. Given Series: 10, 13, 26, 37, 51, 85, 154
2. Calculating the Differences:
- The difference between 10 and 13 is 3.
- The difference between 13 and 26 is 13.
- The difference between 26 and 37 is 11.
- The difference between 37 and 51 is 14.
- The difference between 51 and 85 is 34.
- The difference between 85 and 154 is 69.
3. Identifying the Pattern:
- By analyzing the differences between consecutive numbers, we can see that there is no consistent pattern or progression.
- The differences vary significantly from one pair of numbers to the next.
4. Finding the Wrong Number:
- The wrong number in the series is typically the one that does not follow the established pattern or rule.
- In this case, the number 154 stands out as it deviates significantly from the previous differences in the series.
5. Correcting the Series:
- To correct the series, we can try to establish a new pattern or rule that is consistent with the given numbers.
- One possible correction could be replacing the number 154 with a number that follows a more logical progression based on the differences between consecutive numbers.
6. Conclusion:
- By carefully analyzing the given series and calculating the differences between consecutive numbers, we can identify the wrong number (154) and propose a correction to establish a more logical pattern in the series.
