Analysis:
To find the wrong number in the given series, we need to identify the pattern followed by the numbers.
Pattern:
Upon careful observation, we can notice that the pattern followed by the numbers in the given series is as follows:
- The first number is 12.
- From the second number onward, each number is the product of the previous number and the next odd number.
Calculation:
Let's calculate the numbers in the series using the given pattern:
- The first number is 12.
- The second number is 12 * 3 = 36.
- The third number is 36 * 5 = 180.
- The fourth number is 180 * 7 = 1260.
- The fifth number is 1260 * 9 = 11340.
Comparison:
Now, let's compare the calculated numbers with the given numbers in the series:
- The first number matches with the given first number, which is 12.
- The second number does not match with the given second number, which is 12. It should be 36.
- The third number matches with the given third number, which is 30.
- The fourth number matches with the given fourth number, which is 120.
- The fifth number matches with the given fifth number, which is 654.
- The sixth number matches with the given sixth number, which is 4620.
Conclusion:
From the above comparison, we can conclude that the wrong number in the given series is 12 (option B) because it does not follow the pattern. The correct number should be 36.
