1.In the following question, one term in the number series is wrong. Find out the wrong term. 105, 85, 60, 30, 0, - 45, - 90
TCS 2022
a) 0
b) -45
c) 105
d) 60
33.33 % | 66.67 %
Correct Answer:
0 To identify the pattern and find the wrong term in the number series, lets analyze the differences between consecutive terms:
1st difference: 105 - 85 = 20
2nd difference: 85 - 60 = 25
3rd difference: 60 - 30 = 30
4th difference: 30 - 0 = 30
5th difference: 0 - (-45) = 45
6th difference: -45 - (-90) = 45
We observe that the differences alternate between 20, 25, 30, and 45. It seems like the differences increase by 5 each time, then jump to an increment of 15.
However, we also see that the 5th difference is 45 and the 6th difference is also 45, which is an inconsistency. This suggests that there might be an error in the sequence.
Lets continue the pattern:
7th difference: -90 - (-135) = 45
This indicates that the sequence may be incorrect from the term "0" onward.
So, the wrong term in the series is "0."
