Answer:
the 8th term is 0.148148148148...
Step-by-step explanation:
-108÷(-324)=0.333333333333 = 1/3
(-36)÷(-108)=0.333333333333
(-12)÷(-36)=0.333333333333
then the common ratio of the sequence is 1/3
then
the 5th term is 12×(1÷3) = 4
the 6th term is 4×(1÷3) = 1.333333333333
the 7th term is 1.333333333333×(1÷3) = 0.444444444444
the 8th term is 0.444444444444×(1÷3) = 0.148148148148
