8 12 18 27
here is the pattern
12-8=4
18-12=6
27-18=9
you add 2 to 4 to get 6, you add 3 to 6 to get 9 therefore you need to add 4 to 9 which is equal to 13
the next number (x) minus 27 should have a difference of 13
x-27=13
x=40

I think ptolemy862000 has the right idea.
The sequence is : 8, 12, 18, 27, ...
Take the first differences : 4, 6, 9, ...
Now take the second differences : 2, 3, ...
Assuming the next second difference is 4,
then the next first difference will be 13,
which means the next number in the sequence will be 40.

This is a geometric sequence, where r = 3/2.
8, 12, 18, 27,
The next number is obtained by multiplying the previous number by 3/2, or 1.5. The next number is 40.5, or 81/2.

8 = 4(2)
12 = 4(3)
18 = 9(2)
27 = 9(3)
4 and 9 are perfect squares, the next is 16, so perhaps the next number is
16(2) = 32 followed by
16(3) = 48

2*4=8
3*4=12
2*9=18
3*9=27
now since 4&9 are first two perfect sq. &the next are 16 &25&so on
thus,the next no.s will be
2*16=32
3*16=48
2*25=50
3*25=75
and so on..............................

I've got several ideas:
Could be 32
2^2 x 2, 2^2 x 3, 3^2 x 2, 3^2 x 3, etc...
