The logic of this series is that the sum of two numbers makes the third one in the series. This we can observe by seeing 28+84=112, 84+112=196 and so on. The only number that does not satisfy this logic is 308 +504, which should be 812 and not 872. Thus, 872 is the wrong number in the series.

Explanation:

To find the wrong number in the given series, we need to observe the pattern and identify any inconsistencies in the sequence. Let's analyze the given series step by step:

Step 1: 28, 84
The first term is multiplied by 3 to get the second term. (28 * 3 = 84)

Step 2: 84, 112
The second term is added by 28 to get the third term. (84 + 28 = 112)

Step 3: 112, 196
The third term is multiplied by 2 to get the fourth term. (112 * 2 = 224)

Step 4: 196, 308
The fourth term is added by 28 to get the fifth term. (196 + 28 = 224)

Step 5: 308, 504
The fifth term is multiplied by 2 to get the sixth term. (308 * 2 = 616)

Step 6: 504, 872
The sixth term is added by 28 to get the seventh term. (504 + 28 = 532)

Identifying the wrong number:
By following the pattern, we can see that the correct seventh term should be 532, not 872. Therefore, the wrong number in the given series is 872.

Summary:
The series follows a pattern where each term is either multiplied by 3 or 2, and sometimes 28 is added to the previous term. By analyzing the pattern, we can determine that the wrong number in the series is 872.
