Tetrahedral Number - Representing Pyramid with Triangular base
                 
                          
                   Pyramid with triangular base is known as tetrahedron, tetrahedron numbers are 1, 4, 10, 20, 35, 56, 84, 120, 165, 220, 286, 364, 455, 560, 680, 816, 969, this online calculator has been developed to calculate tetrahedral numbers.

                       Formula Used:
Tetrahedral Number (Tn) = ( n × (n+1) × (n+2) ) / 6
Where, 
    
n - Non-Negative Numeral
