3, -6, 12, 4, 20, ?
The next number in the pattern is 324. Each number in the pattern is obtained by multiplying the previous number by 3.
120 (assuming the pattern is x3, +1, x3, +1...)
44
20 alternate numbers and double difference 6 / 8 / 12 = +2 / +4 / so +8 next = 12 + 8 = 20 (3 / 4 / 6 / 10 = +1 / +2 / +4 / so same again = 10 + 8 = 18 3 6 4 8 6 12 10 20 18 36 34 68 66
3, -6, 12, 4, 20, 13, 27, 21, 33 -9, +18, -8, +16, -7, +14, -6, +12
3, -6, 12, 4, 20, ?
what is the pattern for the following 3, -6, 12, 4, 20

12/20=6/10=3/5 Do you see the pattern?

I think that the next number in this pattern is twelve. I think that the pattern is 1/2, 2/3. 3/4, 4/5 and so on.
13 is one possibility.
