What is the difference between a geometric sequence and an infinite geometric series?

Short Answer

Expert verified
A geometric sequence is a list of numbers with a specific pattern, where each term is obtained by multiplying the previous term by a fixed, non-zero number known as the ratio. An infinite geometric series is the sum of the terms in an infinite geometric sequence. The geometric sequence does not necessarily need to have a sum, whereas an infinite geometric series does, as long as the common ratio is within the interval (-1,1).

Step by step solution

01

Define Geometric Sequence

A geometric sequence is a sequence of numbers where each term after the first is obtained by multiplying the previous term by a fixed, non-zero number known as the ratio. So, if you were to have a sequence: a, ar, ar^2, ar^3, ..., ar^(n-1), this would be considered a geometric sequence, where a is the first term, r is the common ratio, and n is the total number of terms in the sequence.
02

Define Infinite Geometric Series

An infinite geometric series, on the other hand, is the sum of the terms in an infinite geometric sequence. Given the ratio, r, is in the interval (-1,1), the sum, S, of the infinite geometric series a + ar + ar^2 + ar^3 + ... is given by the formula S = a/(1 - r), where a is the first term and r is the common ratio.
03

Identify the Differences

The main difference between a geometric sequence and an infinite geometric series is that a geometric sequence is a list of numbers with a specific pattern, while an infinite geometric series is the sum of the terms within an infinite geometric sequence. Additionally, a geometric sequence does not necessarily need to have a sum while an infinite geometric series does, as long as the common ratio is within the interval (-1,1).

Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. I used a formula to find the sum of the infinite geometric series \(3+1+\frac{1}{3}+\frac{1}{9}+\cdots\) and then checked my answer by actually adding all the terms.

Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. In order to expand \(\left(x^{3}-y^{4}\right)^{5},\) I find it helpful to rewrite the expression inside the parentheses as \(x^{3}+\left(-y^{4}\right)\).

Use the formula for the value of an annuity to solve Exercises. Round answers to the nearest dollar. To save money for a sabbatical to earn a master's degree, you deposit \(\$ 2000\) at the end of each year in an annuity that pays \(7.5 \%\) compounded annually. a. How much will you have saved at the end of five years? b. Find the interest.

Use the Binomial Theorem to find a polynomial expansion for each function. Then use a graphing utility and an approach similar to the one in Exercises 69 and 70 to verify the expansion. $$f_{1}(x)=(x+2)^{6}$$

Solve: \(2 x^{2}=4-x\).
