The correct Answer is:
To find the wrong term in the series 3, 5, 8, 17, 33, 58, 94, we will analyze the differences between consecutive terms and look for a pattern. ### Step-by-Step Solution: 1. **Write down the series:** The given series is: \[ 3, 5, 8, 17, 33, 58, 94 \] 2. **Calculate the differences between consecutive terms:** - Difference between 5 and 3: \(5 - 3 = 2\) - Difference between 8 and 5: \(8 - 5 = 3\) - Difference between 17 and 8: \(17 - 8 = 9\) - Difference between 33 and 17: \(33 - 17 = 16\) - Difference between 58 and 33: \(58 - 33 = 25\) - Difference between 94 and 58: \(94 - 58 = 36\) So, the differences are: \[ 2, 3, 9, 16, 25, 36 \] 3. **Identify the pattern in the differences:** The differences can be expressed as: - \(2 = 1^2 + 1\) - \(3 = 1^2 + 2\) - \(9 = 3^2\) - \(16 = 4^2\) - \(25 = 5^2\) - \(36 = 6^2\) We notice that the differences seem to follow a pattern of squares: - The first difference should ideally be \(2 = 1^2 + 1\) - The second difference should ideally be \(4 = 2^2\) - The third difference is \(9 = 3^2\) - The fourth difference is \(16 = 4^2\) - The fifth difference is \(25 = 5^2\) - The sixth difference is \(36 = 6^2\) 4. **Check for consistency in the differences:** The expected differences should have been: \[ 2, 4, 9, 16, 25, 36 \] However, we have \(3\) instead of \(4\) as the second difference. 5. **Identify the wrong term:** Since the second term (5) should have been \(4\) to maintain the pattern, we conclude that the wrong term in the series is \(5\). ### Conclusion: The wrong term in the series is: \[ \text{5} \]
