Answer 1

4 is the wrong number in the given series.

Given:

4,7,12,19,31,50,81

To find:

find the wrong number from the series​

Solution:

Given series is 4,7,12,19,31,50,81

Observe the given sequence carefully. we can see that the obtained numbers are the difference of the next two digits.

Following is the process of how the series is formed:

=> 12 - 7 = 5 (4 is written instead of 5)

=> 19 - 12 = 7

=> 31 - 19 = 12

=> 50 - 31 = 19

=> 81 - 50 = 31

Hence. the wrong number in the series is 4

$\large\bf{\underline{\red{SOLUTION:-}}}$

Observe the given sequence carefully. we can see that the obtained numbers are the difference of the next two digits.

Let See How that will Happen:-

12 - 7 = 5 (But Here We Cannot Get that Number)

19 - 12 = 7

31 - 19 = 12

50 - 31 = 19

81 - 50 = 31

So, The Wrong Number in the Series is 4.
