A Sequence is a set of things (usually numbers) that are in order.
A Sequence is a set of things (usually numbers) that are in order. Each number in the sequence is called a term (or sometimes "element" or "member")
In an Arithmetic Sequence the difference between one term and the next is a constant.
In other words, we just add the same value each time infinitely.
1,4,7,10,13,16,...
In general we could write an arithmetic sequence like this:
{a, a+d, a+2d, a+3d, ... }
where:
We can write an Arithmetic Sequence as a rule:
n = a + d(n−1)
