Finding the 𝒏th term of an arithmetic sequence - KS3 Maths

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 Arithmetic sequences The simplest sequence is the sequence (0, 1, defined by g n for every n e N In general, an arithmetic sequence is specified by

Arithmetic Sequences If the terms of a sequence differ by a constant, we say the sequence is arithmetic If the initial term of the sequence is a a If the first term of the sequence is a and the common difference is d, then the arithmetic sequence can be written as a, a+d, a+2d, a+3d, …, a+d, …

Finite arithmetic series Tn is the nth term of the sequence; When we sum a finite number of terms in an arithmetic sequence, we get a finite This algebra video discusses the math formulas used when dealing with arithmetic sequences
