Arithmetic Sequence

Arithmetic Sequence arithmetic sequence A sequence such as 1, 5, 9, 13, 17 or 12, 7, 2, –3, –8, –13, –18 which has a constant difference between terms The first term is a1, the common difference is d arithmetic sequence Arithmetic sequences are also known as linear sequences because, if you plot the position on a horizontal axis and the term on the vertical axis, you get a

arithmetic sequence The standard form of arithmetic sequences can be expressed as: a , a + d , a + 2 d , a + 3 d , a + 4 d , a + 5 d a represents the first term and is

arithmetic sequence The sum of the arithmetic sequence formula says S_n = n2 S_n = n2 (2a + d), where a_1 a is the first term and d is the Find the Sum of the First n Terms of an Arithmetic Sequence As with the general sequences, it is often useful to find the sum of an arithmetic
