Incorrect Term: 202
The given series is 1, 1, 2, 7, 34, 202, 1420.
To determine the pattern in the series, let's calculate the differences between consecutive terms:
1 - 1 = 0
2 - 1 = 1
7 - 2 = 5
34 - 7 = 27
202 - 34 = 168
1420 - 202 = 1218
The differences between consecutive terms are not consistent. The first difference is 0, the second difference is 1, the third difference is 5, the fourth difference is 27, the fifth difference is 168, and the sixth difference is 1218.
The pattern in the series is not clear. However, it appears that the differences between consecutive terms are increasing significantly.
Explanation:
- The first term in the series is 1 and it is correct.
- The second term in the series is also 1 and it is correct.
- The third term in the series is 2 and it is correct.
- The fourth term in the series is 7 and it is correct.
- The fifth term in the series is 34 and it is correct.
- The sixth term in the series is 202 and it is incorrect.
The incorrect term breaks the pattern established by the previous terms. As we can see, the differences between the terms are increasing significantly, but the incorrect term 202 does not follow this pattern. It seems to be an outlier.
Conclusion:
Based on the pattern established by the previous terms in the series, the term 202 is placed incorrectly.
