Explanation

The series is 3^2, 4^2, 5^2, 6^2, 7^2. The next term should be 8^2 = 64, not 61.

AI explanation

The series follows a pattern of consecutive perfect squares starting from the square of 3. The terms are 3 squared equals 9, 4 squared equals 16, 5 squared equals 25, 6 squared equals 36, and 7 squared equals 49. The next term should be 8 squared, which is 64, but the given number is 61, making it the wrong term in the series.
