∙ 7y agoJust divide any number in the sequence by the next number in the sequence. To be on the safe side, you may want to check in more than one place - if you get the same result in each case, then it is, indeed, a geometric sequence.

∙ 7y agoA geometric sequence is defined by the next term being the common ration times the current term.
To find the common ratio in a geometric sequence divide any number by the previous number:
125 ÷ 625 = 1/5 = 0.2
25 ÷ 125 = 1/5 = 0.2
5 ÷ 25 = 1/5 = 0.2
1 ÷ 5 = 1/5 = 0.2
If this division does not give the same value each time, then the sequence is not a geometric sequence or you've made a mistake).
For the geometric sequence 625, 125, 25, 5, 1 the common ratio is 0.2

What is the ratio of similar solids when the areas are 125 and 216?
The ratio is sqrt(125/216) = sqrt(0.578704) = 0.7607 (to 4 dp) The question is more likely to have been about volumes being 125 and 216. In that case, the ratio of the solids' dimensions would have been the cuberoot of (125/216) which is 5/6.
What is the geometric mean of 5 and 25?
The geometric mean is a positive number x such that x/5 = 25/x. Thus, x2 = 125, so x = 5*sqrt(5).
The ratio of the corresponding edge lengths of two similar solids is 5 6 what is the ratio of their volumes?
125:216
If two cylinders are similar and the ratio between the lengths of their edges is 2 5 what is the ratio of their volumes?
As volume is length x length x length, cube the ratio of the lengths, thus: Ratio of lengths = 2 : 5 ⇒ Ratio of volumes = 23 : 53 = 8 : 125
What is the next number in the sequence 125 -25 5 -1....?
This is a geometric sequence. Each number is multiplied by the same constant, to get the next number. If you divide any number by the previous one, you can find out what this constant is.
What would the seventh term be in a geometric sequence with a3 equals 125 and r equals 5?
You have the 3rd term and you want to go out four more so multiply by 5 this many times: 125*5^4 = 78125

What is the definition of 125 Loan?
A loan, usually a mortgage, with an initial loan amount equal to 125% of the initial property value. In other words, a 125% loan has a loan-to-value ratio (LTV ratio) of 125%.
What is the ratio of 125 centimeters to 2 meters?
Just convert the units to a common unit. Reminder: 1 meter = 100 centimeters. Then express as a ratio of the same unit. The units cancel in this case.
