Answer 2

Given: The given series is 136, 143, 159, 187, 224, 271.

To find: We have to find the wrong number.

Solution:

The series is 136, 143, 159, 187, 224, 271

The difference between the numbers are respectively-

$143 - 136 = 7 \\ 159 - 143 = 16 \\ 187 - 159 = 28 \\ 224 - 187 = 37 \\ 271 - 224 = 47$

The difference between the numbers is 7, 16, 28, 37, 47.

The difference between the differences are-

$16 - 7 = 9 \\ 28 - 16 = 12 \\ 37 - 28 = 9 \\ 47 - 37 = 10$

10 is not the correct difference between 47 and 37. It is 12.

Thus the number 47 is 49.

Thus wrong number is 271.

The wrong number in the series is 271.
