20
22
The next is 3.
The given pattern appears to alternate between two sequences: one sequence that doubles the previous number (3 to 6 to 12) and another that adds 1 to the previous number (4 to 20). Following this pattern, after 20, the next number in the doubling sequence would be 24, as it continues from 12. Thus, the next number in the pattern is 24.
12
The sequence changes by multiplying with different numbers: from 3 to -6 (* -2), -6 to 12 (* -2), 12 to 4 (* 0.33), and 4 to 20 (* 5). If we continue this pattern, 20 multiplied by 0.5 gives us 10. So, the next number is 10.
The next number in the sequence is 20. You are alternately multiplying the previous number by two and then subtracting two.
12The next number in the sequence is the previous # divided by 3. So, 324/3 = 108; 108/3 = 36; 36/3 = 12
Each following number in the sequence is being divided by 4. Therefore, the next number in the sequence is 3/4 = 0.75.
