In the example given in the picture, the series will be This equation is found to the right of the sigma.

The letter below the sigma is the index of summation, which informs that the index "n" starts out equal to the first number that will be placed into the equation in place of n. The numerical value below the sigma is the first value in the sequence. A sigma ( Σ) is a letter in the Greek alphabet.Īs shown in the picture, the number above the sigma is the last value in the sequence. The sum of an arithmetic sequence can also be written using sigma notation. N, which is the number of terms in the sequence, is multiplied by the average of the first and last terms ((a 1 + a n )⁄2) to calculate the sum of the arithmetic series.

of Arithmetic Sequence: 1,5,9,13,17,21.(increase by 2 each time)ĭefinition: An arithmetic series is the sum of an arithmetic sequence, which is a sequence of numbers in which the difference between the consecutive terms is constant.

Once learned, sequences and series will become a corner stone of higher-level math.Īrithmetic Sequence- A list of numbers in which each term is equal to the previous term, minus or plus a common difference.Ī n-the number term in the sequence (a 1-the first term in sequence)Įx. On this page you will learn the steps necessary to find arithmetic sequences and series. In essence an arithmetic sequence is a set of numbers with a common difference an arithmetic series is the sum of the sequence. For example, architects use them in the creation of buildings, and bee’s honeycombs can be broken down into an arithmetic sequence. These to components of math have important real-life application such as creating or solving a pattern. So if the sequence is 1,3,5 the sum is 9. An arithmetic series on the other hand is the SUM of the sequence. would be an arithmetic sequence with a constant difference of 2. In simplest terms an arithmetic sequence is a pattern in which the first term has a constant difference with consecutive terms. It should be noted that the initial uses of arithmetic sequences and series date back to ancient Egyptian civilizations in their creation of the pyramids. These sequences and series are one of the earliest branches of mathematics.
