A sequence is a collection of numbers and terms.Sequence may be finite and infinite.
Finite sequence :
Infinite sequence :
A pattern of terms or numbers that increase or decrease at a constant amount.
This sequence has a difference of 4 between each number.
We could write like that:
a is the first term, and
d is the difference between them.
$$a = 1$$
$$d = 4$$
