The correct Answer is:
To solve the problem of identifying the odd one out in the series: 3, 5, 7, 12, 13, 17, 19, we can follow these steps: ### Step 1: Identify the Series We start with the series: 3, 5, 7, 12, 13, 17, 19. ### Step 2: Analyze the Numbers Next, we will analyze the numbers to see if there is a common property among them. ### Step 3: Check for Prime Numbers We check which of these numbers are prime: - 3: Prime - 5: Prime - 7: Prime - 12: Not prime (it is even and divisible by 1, 2, 3, 4, 6, 12) - 13: Prime - 17: Prime - 19: Prime ### Step 4: Identify the Odd One Out From our analysis, we can see that all numbers in the series are prime except for 12. Therefore, 12 does not belong to the series of prime numbers. ### Conclusion The odd one out in the series is **12**.
