Buktikan bahwa n^3+5n habis dibagi 6 untuk setiap n bilangan asli

n^3 + 5n = habis dibagi 6

1^3 + 5 = 1+5 = 6 (habis dibagi 6)
2^3 +10 = 8+10 = 18 (habis dibagi 6)
10^3 + 50 = 1000+50 = 1050 (habis dibagi 6)

bisa disimpulkan bahwa persamaan diatas benar.

n = 1
(1)^3+5(1)/6 = 1+5/6 = 6/6 = 1

n = 2
(2)^3+5(2)/6 = 8+10/6 = 18/6 = 3

n = 3
(3)^3+5(3)/6 = 27+15/6 = 42/6 = 7

n = 4
(4)^3+5(4)/6 = 64+20/6 = 84/6 = 14

n = 5
(5)^3+5(5)/6 = 125+25/6 = 150/6 = 25

Dan seterusnya

Maaf jika ada kesalahan :)
