The common ratio of the geometric sequence is:

Step-by-step explanation:
A geometric sequence has a constant ratio 'r' and is defined by

where
Given the sequence

Compute the ratios of all the adjacent terms: 

The ratio of all the adjacent terms is the same and equal to

Therefore, the common ratio of the geometric sequence is:
Answer:
Step-by-step explanation:
11) 
Subtract 4 from both sides. Square each side. Subtract 33 from both sides. Divide each side by 8. Your answer is -3.
12) 
Square both sides. Put all numbers on one side of the equation so that you can be equal to zero. Factor out and solve for x.

Answer:
18 KM/H.
Step-by-step explanation:
S= D / T or 500 meters / 100 seconds. The answer is 5M/S. To calculate the speed per hour, multiply the distance by 3600 (60 seconds times 60 minutes equals one hour). 5 x 36oo = 18 KM/H.
