In the following question, one of the terms in the number series is wrong. Find out the wrong term.
160, 118, 83, 75, 34, 20
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 75
The series falls each time, so the differences between the terms are checked. They are multiples of 7 that go down by 7 each time: 42, 35, 28, 21, 14.
\(160-42=118\)
\(118-35=83\)
\(83-28=55\), but the series has 75
\(55-21=34\)
\(34-14=20\)
Every other term fits, and 34 follows from 55, not from 75. So the term should be 55, and 75 is the wrong term.
