equation to find sum of arithmetic sequence

#EQUATION TO FIND SUM OF ARITHMETIC SEQUENCE PLUS#

To find a formula for the sum, Sn, of the first n terms of an arithmetic sequence. This is an arithmetic series since the difference between any two successive pairs of numbers is 2. Example 1: Determine whether or not the sequence is arithmetic.

More generally, a finite arithmetic sequence with n. each step would be d or the common ratio) are needed to get to the last term. used by Gauss when he was asked as a schoolboy to find the sum of the first hundred natural numbers.

The first four terms of the sequence show that the common difference is 5. The Summation Calculator finds the sum of a given function. Find the common difference in the following arithmetic finite sequence: 2, 7, 12, 17,, 47. Step 1: Enter the formula for which you want to calculate the summation.

Essentially, the last term would just be expressed as the the first term (your starting point) plus however many steps (i.e. A sequence in which all pairs of successive terms have a common difference is called an arithmetic finite sequence.
