The common ratio is the ratio of the nth term (n > 1) to the (n-1)th term. For the progression to be geometric, this ratio must be a non-zero constant.

What do the following numbers have in sequence - 512-256-128-64?
It is a geometric progression with common ratio 0.5
What number is missing from the following sequence 1875-375-75--3?
15. It's a Geometric Progression with a Common Ratio of 1/5 (or 0.2).
How do you find the ratio in the geometric progression?
Divide any term, except the first, by the term before it.
What is the difference between arithmetic progression and geometric progression?
In an arithmetic progression the difference between each term (except the first) and the one before is a constant. In a geometric progression, their ratio is a constant. That is, Arithmetic progression U(n) - U(n-1) = d, where d, the common difference, is a constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1) + d = U(1) + (n-1)*d Geometric progression U(n) / U(n-1) = r, where r, the common ratio is a non-zero constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1)*r = U(1)*r^(n-1).
What is a geometric rule for pattern?
Not sure about this question. But, a geometric sequence is a sequence of numbers such that the ratio of any two consecutive numbers is a constant, known as the "common ratio". A geometric sequence consists of a set of numbers of the form a, ar, ar2, ar3, ... arn, ... where r is the common ratio.

What are scientific words that start with g?
Geology, Geography, Geometry, Gems, Gold, Gadolinium, Gallium, Germanium, Graduated Cylinder, Gametes, Gauges, Geotropism, Gigabytes, Gigapascal, Gluon, and Gravity.
How can you tell if a infinite geometric series has a sum or not?
The geometric series is, itself, a sum of a geometric progression. The sum of an infinite geometric sequence exists if the common ratio has an absolute value which is less than 1, and not if it is 1 or greater.
What is the sum of the first 15 terms of an arithmetic?
For an Arithmetic Progression, Sum = 15[a + 7d].{a = first term and d = common difference} For a Geometric Progression, Sum = a[1-r^15]/(r-1).{r = common ratio }.

How do you find the ratio in the geometric progression?
Divide any term, except the first, by the term before it.
What is the pattern for a half a quarter and an eighth?
It's a geometric progression with the initial term 1/2 and common ratio 1/2. The infinite sum of the series is 1.
What is the difference between arithmetic progression and geometric progression?

Equivalently, U(n) = U(n-1)*r = U(1)*r^(n-1).
Can common ratio be 1 in geometric progression?
if a number is multiplied by 1, then it does not change, it is Still the same number. A ratio of 1 is impossible . The ratio between two quantities must always be greater than 1 otherwise there is no difference between them.
What is the common ratio in this geometric sequence 3 12 48?
The ratio is 4.
What is the change from one number to the next in a geometric sequence called?
The common ratio.
