A series of free, online lessons for Intermediate Algebra Algebra II with videos, examples and solutions. The following diagram gives the Arithmetic Sequence Formula. Scroll down the page for more examples and solutions on how to use the Arithmetic Sequence Formula to find the nth term of the sequence. A list of numbers that follows a rule is called a sequence. Sequences whose rule is the addition of a constant are called arithmetic sequences, similar to geometric sequences that follow a rule of multiplication.

Arithmetic sequences is a part of syllabus in algebra 1 second math course , which finds application in many algebra questions including algebra word problems. An arithmetic progression AP or arithmetic sequence is a sequence of numbers, whose consecutive numbers differ by a constant. When n terms of an arithmetic sequence are added, you get arithmetic series. Learn more about Arithmetic sequences using the resources on this page. Find More….

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant. If the first term of an arithmetic sequence is a 1 and the common difference is d , then the n th term of the sequence is given by:. An arithmetic series is the sum of an arithmetic sequence. We find the sum by adding the first, a 1 and last term, a n , divide by 2 in order to get the mean of the two values and then multiply by the number of values, n:.
In order to assist schools and districts with the implementation of the Common Core, NYSED has provided curricular modules and units in P ELA and math that can be adopted or adapted for local purposes.
