Explanation

The series follows the pattern: multiply by consecutive odd numbers (9, 7, 5, 3, 1) starting from 13: 13 × 9 = 117, 117 × 7 = 819, 819 × 5 = 4095, 4095 × 3 = 12285, 12285 × 1 = 12285. The last term 12300 breaks this pattern as it should be 12285. The sequence systematically decreases the multiplier by 2 each time.
