29, assuming it is an algebraically reclusive sequence.
The series appears to be following a pattern where each number is the result of a mathematical operation on the previous numbers. In this case, the pattern seems to be adding consecutive odd numbers starting from 1. 1 + 8 = 9 9 + 9 = 18 18 + 7 = 25 25 + 2 = 27 27 - 6 = 21 Following this pattern, the next number in the series would be 21 + 1 = 22.
The pattern rule is: 4 5 6 7 8 and so the next number will be 33+9 = 42
18-the correct number should be 20.
The next number in the series 4, 12, 6, 12, 36, 18, 36
The next number in the series 4-12-6-12-36-18-36.. is 108.
