- Sum of the first n whole numbers = n(n - 1)/2
- Sum of the first n natural numbers = n(n - 1)/2
- Sum of the first n even numbers = n(n - 1)
- Sum of the first n odd numbers = n
^{2} - Sum of the first n square numbers = n(n + 1)(2n + 1)/6
- Sum of the first n cube numbers = n
^{2}(n + 1)^{2}/4 - Sum of the first n fourth power numbers = n(n + 1)(2n + 1)(3n
^{2}+ 3n - 1)/30
