A geometric sequence follows a pattern with a common ratio.
Find the ratio between 3 and 9
If you multiply 3 by 3 the answer would be 9.
The common ratio is 3.
Now multiply 9 by 3 to get 27.
The answer is D. 27
B. 16.30 = 16.3
if there is a 0 in a decimal and it is the farthest right place value it is the same as if the 0 wasn't there
X/4 = 4.3/2.5
x/4 = 1.72
x = 1.72 x 4
x = 6.88
