Find the next number in the series 4 8 12 20 --?

To find the next number in the series 4, 8, 12, 20, we need to identify the pattern or rule governing the sequence. In this case, the pattern is that each number is the sum of the previous two numbers. 4 + 8 = 12, 8 + 12 = 20, and 12 + 20 = 32. Therefore, the next number in the series is 32.


What number comes next 3 -6 12 4 20?

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 pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
