The series is decreasing by consecutive perfect squares starting from 16^2 (256) and decreasing by 2^2 each time. Therefore, the next number in the series would be 4^2, which is 16.
24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.

The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.
To find the next number in the series, we can observe the alternating pattern between pairs of numbers. The first number is 14, and it decreases by 3 to 11, then increases by 7 to 18. Following this pattern, the next number after 18 should decrease by 2, resulting in 16. Therefore, the next number in the series is 16.

It is: 16 squared = 256
24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.
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.
