Answer:
The common ratio is -3
Step-by-step explanation:
we know that
In a<u> Geometric Sequence</u> each term is found by multiplying the previous term by a constant called the common ratio
In this problem we have
-2,6,-18,54...
Let
a1=-2, a2=6,a3=-18,a4=54
a2/a1=6/-2=-3
a3/a2=-18/6=-3
a4/a3=54/-18=-3
Each term (except the first term) is found by multiplying the previous term by -3
therefore
we have a geometric sequence and the common ratio is -3
322.4÷40.3 = 8

Answer:
Step-by-step explanation:
Percent change = (Change/Original)
For Week 2 the % change is [(13.5-14)/14]*100%
For week 3 the % change is [(13.1-13.5)/13.5]*100%
Week Time(s) Change % Change
1 14
2 13.5 -0.5 -3.57%
3 13.1 -0.4 -2.96%
The negative value for percent change reflect the drop in time (an improvement, but not a positive number.
