Square Pyramidal Calculation


Calculates the square pyramidal number for entered non-negative real number (n) using following formula :
Square pyramidal number (Pn) = (n(n + 1)(2n + 1))/6
The first few square pyramidal number are 1, 5, 14, 30, 55, 91, 140, 204 ...
Non-Negative Number (n) =
 
 
 
Square Pyramidal Number (Pn) =
