Question of The Day30-09-2019

What will be the wrong number in the given number series, given that the other numbers follows a certain pattern?

17.11, 19.22, 21.44, 23.66, 25.88, 27.10, 30.32

Answer

Correct Answer : c ) 27.10

Explanation :

Consider the given series

17.11, 19.22, 21.44, 23.66, 25.88, 27.10, 30.32

The logic for the above series can be explained as

17.11 = 17 + 0.11

19.22 = 17 + 2 + 0.11*2

21.44 = 17 + 4 + 0.11*4

23.66 = 17 + 6 + 0.11*6

25.88 = 17 + 8 + 0.11*8

17 + 10 + 0.11*10 = 28.10 ≠ 27.10

30.32 = 17 + 12 + 0.11*12

Thus, 27.10 is the wrong term in the given series

Hence, (C) is the correct answer.
