Hey your question seems wrong

According to whatever little i know,
if the expression is -1/2, -3, -18,

Answer will be option D- 6

That's because on simply multiplying each term by 6, you get the next term!

All the best :)

as written it is not a geometric sequence.
If the first term was -1/12 then the answer would be
D
(-1/2)/(-1/12) = (-3/-1/2) = (-18/-3) = 6

I assume the -1/2 should not be repeated so the sequence is -1/2, -3, -18.
The common ratio is 6 because -1/2 * 6 = -3 and -3 * 6 = -18.

6. Was the first term supposed to be -1/12?
