This book uses the You can choose any term of the sequence, and add 3 to find the subsequent term. In this case, the constant difference is 3. The sequence below is another example of an arithmetic sequence. For this sequence, the common difference is –3,400. Each term increases or decreases by the same constant value called the common difference of the sequence. The values of the truck in the example are said to form an arithmetic sequence because they change by a constant amount each year. In this section, we will consider specific kinds of sequences that will allow us to calculate depreciation, such as the truck’s value.

The truck will be worth $21,600 after the first year $18,200 after two years $14,800 after three years $11,400 after four years and $8,000 at the end of five years. The loss in value of the truck will therefore be $17,000, which is $3,400 per year for five years. After five years, she estimates that she will be able to sell the truck for $8,000.

One method of calculating depreciation is straight-line depreciation, in which the value of the asset decreases by the same amount each year.Īs an example, consider a woman who starts a small contracting business. This decrease in value is called depreciation. The book-value of these supplies decreases each year for tax purposes. Use an explicit formula for an arithmetic sequence.Ĭompanies often make large purchases, such as computers and vehicles, for business use.Use a recursive formula for an arithmetic sequence.

Find the common difference for an arithmetic sequence.

Recall that an arithmetic sequence is a sequence in which the difference between any two consecutive terms is the common difference, latexd/latex.The sum of the terms of an arithmetic sequence is called an arithmetic series. The "Unknown Heritage": trace of a forgotten locus of mathematical sophistication. Just as we studied special types of sequences, we will look at special types of series.

Problems involving arithmetic progressions.

Heronian triangles with sides in arithmetic progression.

Generalized arithmetic progression, a set of integers constructed as an arithmetic progression is, but allowing several possible differences.

Inequality of arithmetic and geometric means.

However, the intersection of infinitely many infinite arithmetic progressions might be a single number rather than itself being an infinite progression. The formula for the sum of an arithmetic sequence is: S n n 2 2 a + ( n 1 ) d, where: n the number of terms to be added. If each pair of progressions in a family of doubly infinite arithmetic progressions have a non-empty intersection, then there exists a number common to all of them that is, infinite arithmetic progressions form a Helly family. The intersection of any two doubly infinite arithmetic progressions is either empty or another arithmetic progression, which can be found using the Chinese remainder theorem.

The formula is very similar to the standard deviation of a discrete uniform distribution. Where n n is the number of terms in the progression andĭ d is the common difference between terms. If the initial term of an arithmetic progression is a 1 a_ is an arithmetic progression with a common difference of 2. The constant difference is called common difference of that arithmetic progression. An arithmetic progression or arithmetic sequence ( AP) is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence.
