The object of this study is to search for the general term and the sum of some sequence of numbers by the diagram representing them. We can seek for them easily through intuition than calculation by its method. This very simple method shows us the essential role of the diagram. Therefore, for the more complex sequence of numbers, this study will give you an example of indicating that you can search for its general term and sum by the simple method. And also this paper will show you the relation we obtain in the combination.
