Answers
22.92 is the odd number in the given series.
Given data:
22.22,23.22,22.47,22.92,22.72
To find:
Odd one out!
Explanation:
The absolute difference of two successive numbers should keep on decreasing by 0.25.
22.22 - 23.22 = -1.0 ⇒ absolute(-1.0) = 1.0
23.22 - 22.47 = 0.75 ⇒ absolute(0.75) = 0.75
22.47 - 22.92 = -0.45 [Case failed! The number should be 22.97]
22.92 - 22.72 = 0.20 [Case failed! The number should be 22.97]
Had it been 22.97 in place of 22.92, the absolute differences would have been,
22.47 - 22.97 = -0.50 ⇒ absolute(-0.50) = 0.50
22.97 - 22.72 = 0.25 ⇒ absolute(0.25) = 0.25
So, 22.92 is the wrong number in the given series.
