Yes it's A cos that's the correct answer
Answer:
a(8) = -0.0027
Step-by-step explanation:
The most general formula for a geometric sequence is a(n) = a(1)*r^(n-1), where a(1) is the first term and r is the common ratio.
Here, the formula becomes a(n) = 6*(-1/3)^(n-1).
Substitute 8 for n to find the eighth term:
a(8) = 6*(-1/3)^(8-1), or a(8) = 6(-1/3)^7, or a(8) = -0.0027
Sorry if my handwriting sloppy.
I showed all of it step by step.
0.0091 rounded to the nearest hundredths is 0.01.
I hope this helped!!
The ratio is 14:5, as 42 divided by 3 is 14 and 15 divided by 3 is 5.
