Directions to Solve ...
The given sequence is a combination of two series :
I. 11, 20, 40, 74 and II. 5, 12, 26, 54
The correct pattern in I is + 9, + 18, + 36,.....
So, 40 is wrong and must be replaced by (20 + 18) i.e. 38.

Understanding the Number Series:
To solve this question, we need to analyze the given number series and identify the pattern or rule that is followed in generating the series. Once we identify the pattern, we can determine the wrong term in the series.
Given Number Series: 11, 5, 20, 12, 40, 26, 74, 54
Analyzing the Number Series:
To analyze the given number series, let's list out the terms and observe any patterns or relationships between them.
Term 1: 11
Term 2: 5
Term 3: 20
Term 4: 12
Term 5: 40
Term 6: 26
Term 7: 74
Term 8: 54
Identifying the Pattern:
By observing the given number series, we can see that the pattern is as follows:
- The even-numbered terms (2nd, 4th, 6th, etc.) are obtained by subtracting 6 from the previous term.
- The odd-numbered terms (1st, 3rd, 5th, etc.) are obtained by adding 9 to the previous term.
Applying the Pattern:
Let's apply this pattern to the given number series:
Term 2: 11 - 6 = 5 (Correct)
Term 3: 5 + 9 = 14 (Wrong; should be 20)
Term 4: 20 - 6 = 14 (Correct)
Term 5: 14 + 9 = 23 (Wrong; should be 40)
Term 6: 40 - 6 = 34 (Wrong; should be 26)
Term 7: 26 + 9 = 35 (Wrong; should be 74)
Term 8: 74 - 6 = 68 (Wrong; should be 54)
Identifying the Wrong Term:
From the above calculations, we can see that the wrong terms in the given number series are:
Term 3: 20 (Should be 14)
Term 5: 40 (Should be 23)
Term 6: 26 (Should be 34)
Term 7: 74 (Should be 35)
Term 8: 54 (Should be 68)
Conclusion:
Therefore, the wrong term in the given number series is 40, which corresponds to option C.
