The given number series is as follows-
11, 18, 29, 42, 59, 80, 101
Here, in this series, the following pattern is followed-
11 + 7 = 18
18 + 11 = 29
29 + 13 = 42
42 + 17 = 59
59 + 19 = 78 ≠ 80
78 + 23 = 101
So, 80 is the wrong number.

In the following number series only one number is wrong. Find out the...
The given number series is 11, 18, 29, 42, 59, 80, 101.
To find the wrong number in the series, we need to identify the pattern or rule followed by the numbers in the series.
Observing the series, we can see that the difference between consecutive terms is increasing by 1 each time. Let's calculate the differences:
18 - 11 = 7
29 - 18 = 11
42 - 29 = 13
59 - 42 = 17
80 - 59 = 21
101 - 80 = 21
From the differences, we can see that the pattern is as follows: +7, +11, +13, +17, +21. The difference is increasing by 4 each time.
Now, let's check if the last term in the series, 101, follows the same pattern.
101 + 21 = 122
So, according to the pattern, the next term should be 122. However, the given series does not have a term with the value 122. Therefore, the wrong number in the series is 101.
Hence, the correct answer is option E) None of these.
