It is 30; the first, third, and fifth numbers form the sequence 12, 18, 24. The second, fourth, and sixth numbers follow the sequence 11, 14, 17. Logically, the seventh number must be 24 + 6, so 30.

How about: 18-6 = 12 and 2*12 = 24

30, 20, 36, 23, 42, 26
The answer depends on where in the sequence the missing number is.The sequence could be:-108, 12, 24, 36, 96, 19212, 36, 24, 36, 96, 19212, 24, 18, 36, 96, 19212, 24, 36, 54, 96, 19212, 24, 36, 96, 180, 19212, 24, 36, 96, 192, 252So take your pick. And next time, please try to specify where the missing number should be!

Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30

6, 12, 18, 24, 30,
The number is 18. Let x be the number, The equation is (x-6) * 2 = 24 2(x-6) = 24 2x -12 = 24 2x = 24 + 12 2x = 36 x = 18
How about: 18-6 = 12 and 2*12 = 24
