Macam-macam deret bilangan

 deret bilangan asli:

1 + 2 + 3 + ... + n = n(n+1)/2

deret bilangan ganjil:

1 + 3 + 5 + ... + (2n-1) = n^2

deret bilangan genap:

2 + 4 + 6 + ... + 2n = n(n+1)

deret bilangan persegi:

1 + 4 + 9 + ... + n2 = n(n+1)(2n+1)/6

deret bilangan segitiga:

1 + 3 + 6 + ... + n(n+1)/2 =  n ( n + 1 ) ( n + 2 )/6

deret bilangan persegi panjang:

2 + 6 + 12 + ... + n(n+1) =   n ( n + 1 ) ( n + 2 )/3

deret bilangan kubik:

1 + 8 + 27 + ... + n3 = [n(n+1)/2]2

deret bilangan balok:

6 + 24 + 60 + ... + n( n + 1 )( n + 2 ) = n( n + 1 )( n + 2 )( n + 3 )/4

deret bilangan asli pangkat empat:

1 + 16 + 81 + ... + n4 = n(n+1)(6n3 +9n2 +n - 1)/30
