Arithmetic Sequences

An Arithmetic sequences, or arithmetic progression,is a sequence whose terms go up or down by constant steps.

The inductive definition for an arithmetic sequence has the form :

 where the number d is called the common difference.

Eg 1:                1    3    5    7    9  ...
                     first term a = 1 and common difference d = 3.

Eg 2:                1    4    5    7    8 ...

                     This is not an arithmetic sequences. No solutions,
