A sequence is list of numbers where the same operation(s) is done to one number in order to get the next.Arithmetic sequences specifically refer to sequences constructed by adding or subtracting a value – called the common difference – to get the next term. OK, so I have to admit that this is sort of a play on words since each element in a sequence is called a term, and we’ll talk about the terms (meaning words) that are used with sequences and series, and the notation. N= whichever term of the sequence you want.
