Is there a common ratio for the geometric sequence and what are the missing terms?
2, -4, -16, -36..

No common ratio, thus no geometric sequence

however the 2nd, 3rd and 4th form the pattern:
-(consecutive even)^2
but then the first term does not follow this pattern.

I don't see anything else

Thank you @Reiny
