Explanation

The series consists of pairs (n^2, n). 49=7^2, 7; 64=8^2, 8; 169=13^2, 13.

AI explanation

The series alternates between perfect squares and their square roots, as seen with 49 paired with 7 and 64 paired with 8. Following this logic, the missing number must be 13 squared, which is 169. The result is 169.
