Question

find out the incorrect number in the number series 324,192,92,46,16,4,2.​

Answer 1

92 is the incorrect number in this series

Answer 2

Answer:

The incorrect number is 92.

Step-by-step explanation:

Consider the provided series.

324,192,92,46,16,4,2.​

We need to determine the wrong number.

We don't know which one is wrong, so start finding patter from the lowest number.

4-2 = 2

16-4 = 12

46-16 = 30

92-46 = 46

192-92 = 100

324-192 = 132

Now the we can rewrite the above calculation as shown:

4-2 = 2 = 1×2

16-4 = 12 = 3×4

46-16 = 30 = 5×6

92-46 = 46 ≠ 7×8

192-92 ≠ 9×10

324-192 = 11×12

Here we can observe that the first error starts from 92.

The number should be 102 instead of 92.

102-46 = 56 = 7×8

Hence, the incorrect number is 92.
