Answer may be 6.
For 6 * 11 = 66; 6 * 6 = 36: 6 * 3 = 18; 6 * 1 = 6.
Now (11 - 6) = 5, (6 - 3) = 3, (3 - 1) = 2.
And,
5 - 3 = 2: and 2 - 1 = 1.

Nine may be the answer, the reason is that.
6 + 6 = 12 * 3 = 36 which is next term.
3 + 6 = 9 * 2 = 18 again it is next term.
1 + 8 = 9 * 1 = 9, it may be the answer.
6 + 6 = 12 * 3 = 36 which is next term.
3 + 6 = 9 * 2 = 18 again it is next term.
1 + 8 = 9 * 1 = 9, it may be the answer.

Answer may be 6..
The reason is
differences between two consequitive number are ..
30=5^2+2,18=4^2+2,....so next differences should 12=3^2+5

again multiply 3*6=18 which is next term,
finally multiply 1*8=8 which is the result.
