Explanation

The series alternates between squares and their square roots: 4 (2²), 196 (14²), 16 (4²), 169 (13²), ? (6²=36), 144 (12²), 64 (8²). The square roots follow the pattern: 2, 14, 4, 13, 6, 12, 8. The odd positions increase by 2 (2→4→6→8) and even positions decrease by 1 (14→13→12). The missing term is the square of 6.
