Explanation

The series consists of squares: 15^2=225, 13^2=169, 12^2=144, 10^2=100, 8^2=64. The next should be 6^2=36, but 48 is given.

AI explanation

The pattern of the series consists of the squares of consecutive even numbers arranged in descending order. The terms are 15 squared, 14 squared, 13 squared, 12 squared, 10 squared, and 8 squared. The term 48 breaks this pattern, as it should be the square of 11, which is 121.
