Abstract and 1 Introduction and Description of Results
2. Proof of Results and References
In the proof of both theorems, we use induction.
using properties of Pascal triangle, we get
The statement for k + 1 is also true, and the proof is completed.
using properties of the trinomial coefficients, we get
The statement for k + 1 is also true, and the proof is completed.
The hockey stick theorem in the trinomial triangles has been proved. This theorem can be translated in Pascal pyramid as follows :
Other similar theorems might be obtained for Pascal’s four dimensional and even n-dimensional pyramid.
