A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What are a geometric sequence?

A geometric sequence is an ordered set of numbers such that (after the first number) the ratio between any number and its predecessor is a constant.

What is the common ratio in this geometric sequence 7?

A single number does not constitute a sequence.

What is the common ratio of the geometric sequence 625 125 25 5 1?

Just 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.

What is infinite geometric sequence?

An example of an infinite geometric sequence is 3, 5, 7, 9, ..., the three dots represent that the number goes on forever.

What is the difference between an arithmetic sequence and a geometric sequence?

In an arithmetic sequence the same number (positive or negative) is added to each term to get to the next term.In a geometric sequence the same number (positive or negative) is multiplied into each term to get to the next term.A geometric sequence uses multiplicative and divisive formulas while an arithmetic uses additive and subtractive formulas.

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.

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.

Algebra words that start with g?

· Geometric Sequence (geometric progression) - a sequence of numbers in which each term is obtained by multiplying the preceding term by the same number (common ratio). The following is a geometric progression: 1, 2, 4, 8, 16, 32… The common ratio for this geometric progression is 2.

What are mathamatical patterns?

Mathematical patterns are lists number that follows a certain rule and have different types. Some of these are: Arithmetic sequence, Fibonacci sequence and Geometric sequence.

How do you determine if a sequence is geometric?

A sequence is geometric if each term is found by mutiplying the previous term by a certain number (known as the common ratio). 2,4,8,16, --> here the common ratio is 2.

Is this an arithmetic sequence or a geometric sequence 13 23 33 43 53?

Arithmetic- the number increases by 10 every term.

What is the missing number 111214 2126?

There is no simple answer because the position of the missing number is not known. Furthermore, it is not clear whether the sequence is an arithmetic, geometric or some other sequence.

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.

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 describes the sequence 1 1 2 3 5 is it arithmetic or geometric?

It is an arithmetic sequence. To differentiate arithmetic from geometric sequences, take any three numbers within the sequence. If the middle number is the average of the two on either side then it is an arithmetic sequence. If the middle number squared is the product of the two on either side then it is a geometric sequence. The sequence 0, 1, 1, 2, 3, 5, 8 and so on is the Fibonacci series, which is an arithmetic sequence, where the next number in the series is the sum of the previous two numbers. Thus F(n) = F(n-1) + F(n-2). Note that the Fibonacci sequence always begins with the two numbers 0 and 1, never 1 and 1.

What is the next number 2 7?

It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.

What is ascending geometric sequence?

A geometric sequence is : a•r^n which is ascending if a is greater than 0 and r is greater than 1.
