Find out the wrong term in the given number series.
9, 14, 19, 25, 32, 40
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 9
Look at the differences between neighbouring terms.
Differences: 14 − 9 = 5, 19 − 14 = 5, 25 − 19 = 6, 32 − 25 = 7, 40 − 32 = 8
From 14 on, the differences go up by 1 each time (5, 6, 7, 8), so the first difference should be 4
The first term should be \(14-4=10\), giving 10, 14, 19, 25, 32, 40; the term 9 is wrong
