Arithmetic Series (or progression) = a series where each term is obtained by adding on a constant to the previous term.
The series goes up in equal steps.
The constant is called the common difference (d).
e.g 1+3+5+7+9+... is an arithmetic series.
the common difference (d) = 2
the formula for the nth term is 2n - 1
(2k - 1)
If you are asked to add up all of the terms between 1 and 0, for example, thsi…
