Answer:
Step-by-step explanation:
it is not geometric, as 1/(-1)=-1 and 4/1=4,8/4=2
common ratio is different.
The given sequence is not geometric because they don't have a common ratio.
A geometric sequence is set of numbers which have a common ratio. The next number in a geometirc sequence is the multiple of the previous number.
-1/1 = -1
4/1 = 4
8/4 = 2
The numbers don't have a common ratio.
Thus, we can conclude that the given sequence is not geometric because they don't have a common ratio.
