ANSWER: The next composite number after 12 is 14.
Since each number is one less than the one before it, the next number would be 8.
The series 1318162119 appears to be a sequence where each number is formed by concatenating the first few even numbers. The pattern is: 2 (2), 4 (4), 6 (6), 8 (8), 10 (10), 12 (12), 14 (14), and 16 (16). Following this pattern, the next even number is 18, which would be represented as "18" in the series. Thus, the next number in the series is 20, resulting in the next sequence being 131816211920.
