Description
- This function gives the Arithmetic series of the numbers.
- An arithmetic series is the sum of a sequence {a_k}, k=1, 2, ..., in which each term is computed from the previous one by adding (or subtracting) a constant d.
- Therefore, for k>1,

.
- The sum of the sequence of the first n terms is then given by
