Explanation

The sequence consists of prime numbers: 23, 31, 41, 47, 53, 59, 61, 67. 57 is not prime (3 * 19 = 57).

The sequence lists consecutive prime numbers starting from 23, continuing with 29, 31, 37, 41, 43, 47, 53, and 59. Because 57 is divisible by 3 and is not prime, it is the incorrect term in the sequence.
