The sequence presented consists of five numbers: 3, 6, 12, 4, and 20. It is structured in such a way that the first number is decreased by 9 to reach the second number, an addition of 18 to the previous number yields the third number, and so on. This alternating pattern of subtraction and addition continues throughout the sequence. For example, starting with the first number 3, we subtract 9 to arrive at -6, then we add 18 to get 12, subtract 8 to find 4, and finally add 16 to complete the cycle at 20. The next number in this sequence would be achieved by first subtracting 7 (as the previous number was 20 and the pattern alternate subtraction and addition). This results in the number 13. Following that, the sequence would continue with a subtraction of 6, an addition of 14, a subtraction of 5, and so on, creating a continuous and alternating sequence of additions and subtractions.
