Whether you're finding the nth term or the sum of an arithmetic sequence, our tool delivers results promptly. Our calculator performs quick and accurate calculations, saving you significant time. Why Choose Our Arithmetic Sequence Calculator? The key difference is that a sequence is a list of elements, while a series is a sum of elements. The sum $$$S_n $$$ of the first $$$n $$$ terms of an arithmetic sequence can be calculated using the formula: $$S_n=\frac $$$, the corresponding series would be $$$1+2+3+4+5+\ldots $$$. So the 5th term of the sequence is $$$19 $$$. Using the above example, if we want to find the 5th term $$$\left(n=5\right) $$$, we substitute these values into the formula: $$a_5=3+4\cdot(5-1)=3+16=19 $$ Here, $$$a_n $$$ denotes the nth term, $$$a_1 $$$ is the first term, $$$d $$$ is the common difference, and $$$n $$$ is the term number. The general formula to find the nth term of an arithmetic sequence is: $$a_n=a_1+d(n-1) $$ You can see that each term in the sequence is $$$4 $$$ more than the previous term. Where $$$a_1 $$$ is the first term, and $$$d $$$ is the common difference between the terms.įor instance, consider an arithmetic sequence $$$3,7,11,15,\ldots $$$. This difference is typically referred to as the "common difference."Īn arithmetic sequence is usually written in the form: $$a_1,a_1+d,a_1+2d,a_1+3d,a_1+4d,\ldots, $$ The calculator will immediately provide the desired result.Īn arithmetic sequence, also known as an arithmetic progression, is a sequence of numbers in which the difference between two consecutive terms is constant. How to Use the Arithmetic Sequence Calculator?Įnter the information you have: term numbers (positions of the terms in the sequence), term values, common difference, sum values, etc.Īfter inputting all the information, click on the "Calculate" button. Make arithmetic sequence calculations a breeze with our user-friendly online calculator. Ideally suited for understanding and calculating arithmetic sequences, this tool helps you quickly discover the nth term or compute the sum of an arithmetic sequence. Your arithmetic sequence calculations just got easier with our Arithmetic Sequences Calculator.
