D Correct answer
Explanation

The pattern is: 12+13=25, 13+25=38, 25+38=63, 38+63=101. The series should be 12, 13, 25, 38, 63, 101, 164, 265. The number 104 is incorrect.

AI explanation

The series follows a Fibonacci-style pattern where each term is the sum of the two preceding terms, such as 12 + 13 = 25, 13 + 25 = 38, and 25 + 38 = 63. Continuing this logic, 38 + 63 equals 101, which means 104 is the wrong term. Adding the next two correct terms gives 63 + 101 = 164 and 101 + 164 = 265, confirming the result.
