Tetrahedral Pyramid Number Calculator

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.

Tetrahedral Number Calculation

  • Non-Negative Number (n) =

  •  

     
  • Tetrahedral Number (Tn) =

    indication

Formula Used:
Tetrahedral Number (Tn) = ( n × (n+1) × (n+2) ) / 6

Where,
    n - Non-Negative Numeral

Calculation of tetrahedral / triangular pyramidal numbers is made easier here.
