Answer:
We conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.
Step-by-step explanation:
Given the sequence
2, -4, -16, -36,...
- A geometric sequence has a constant ratio 'r'.
Let us compute the ratio of all the adjacent terms
It is clear that the ratio is not constant.
Thus, the given sequence is not a geometric sequence.
Therefore, we conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.
