A geometric sequence (aka Geometric Progression or GP) is one where each term is the previous term multiplied by a constant (the common difference)
As division is the inverse of multiplication, each term can also be said to be the previous term divided by the reciprocal of the constant.
The sum Sn of n terms of a GP can be found by:
Sn = a(1 - rⁿ)/(1 - r) = a(rⁿ - 1)/(r - 1)
where:
a is the first term
r is the common difference
n is the number of terms
If the value of the common difference is between -1 and 1 (ie |r| < 1), then the sum of the GP will be finite since as n→ ∞ so rⁿ → 0, and will be:
S = a/(1 - r)

Which term describes a function in which the y-values form a geometric sequence?
A function in which the y-values form a geometric sequence is referred to as a geometric function. In such functions, each successive value is obtained by multiplying the previous value by a constant ratio. This characteristic means that for a given input, the output values follow a specific pattern defined by the geometric sequence.
What does geometric sequence?
You mean what IS a geometric sequence? It's when the ratio of the terms is constant, meaning: 1, 2, 4, 8, 16... The ratio of one term to the term directly following it is always 1:2, or .5. So like, instead of an arithmetic sequence, where you're adding a specific amount each time, in a geometric sequence, you're multiplying by that term.
Is this arithmetic or geometric 2 4 8 16?
The sequence 2, 4, 8, 16 is a geometric sequence. In a geometric sequence, each term is obtained by multiplying the previous term by a constant factor. In this case, each term is multiplied by 2 (2 × 2 = 4, 4 × 2 = 8, 8 × 2 = 16).
Is geometric sequence a sequence in which each successive terms of the sequence are in equal ratio?
Yes, that's what a geometric sequence is about.
Is a geometric progression a quadratic sequence?
A geometric sequence is : a•r^n while a quadratic sequence is a• n^2 + b•n + c So the answer is no, unless we are talking about an infinite sequence of zeros which strictly speaking is both a geometric and a quadratic sequence.
Determine if the sequence below is arithmetic or geometric and determine the common difference/ ratio in simplest form 300,30,3?
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 10.

Is the sum of two geometric sequence a geometric sequence?
No.
What is found by multiplying the previous term by the same number?
If I understand your question, you are asking what kind of sequence is one where each term is the previous term times a constant. The answer is, a geometric sequence.
Is geometric sequence a sequence in which each successive terms of the sequence are in equal ratio?
Yes, that's what a geometric sequence is about.
What is a shifted geometric sequence?
a sequence of shifted geometric numbers
What is the inverse operation of multiplying by 2?
The inverse of multiplying is dividing, so dividing by 2.
Is a geometric progression a quadratic sequence?
A geometric sequence is : a•r^n while a quadratic sequence is a• n^2 + b•n + c So the answer is no, unless we are talking about an infinite sequence of zeros which strictly speaking is both a geometric and a quadratic sequence.
Who invented geometric sequence series?
antonette taño invented geometric sequence since 1990's
Is dividing by 100 the same as multiplying by 0.1?

Descending geometric sequence?
A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
What is descending geometric sequence?
A geometric sequence is a sequence where each term is a constant multiple of the preceding term. This constant multiplying factor is called the common ratio and may have any real value. If the common ratio is greater than 0 but less than 1 then this produces a descending geometric sequence. EXAMPLE : Consider the sequence : 12, 6, 3, 1.5, 0.75, 0.375,...... Each term is half the preceding term. The common ratio is therefore ½ The sequence can be written 12, 12(½), 12(½)2, 12(½)3, 12(½)4, 12(½)5,.....
