Arithmetic sequences Year 11 Maths

arithmetic sequence  Arithmetic sequences A sequence in which each term changes from the last by adding a constant amount is called an arithmetic sequence We refer to the An arithmetic sequence is a sequence of numbers which increases or decreases by a constant amount each term

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, … If the sequence has a common difference, it is arithmetic; if it has a common ratio, it is geometric We can therefore determine whether a sequence is

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same  If you're given the first few terms of an arithmetic sequence, you just need to identify the first term and the common difference (the number being added each
