Untuk konfigurasi
4, 8, 12, 16, 20, 24, .....
rumusnya Un = 4n
Sebab
4(1), 4(2), 4(3), 4(4), 4(5), 4(6),....
= 4, 8, 12, 16, 20, 24, .....
Untuk konfigurasi
4, 9, 14, 19, 24, ....
rumusnya Un = 5n-1
Sebab
5(1)-1, 5(2)-1, 5(3)-1, 5(4)-1, 5(5)-1
= 5-1, 10-1, 15-1, 20-1, 25-1
= 4 9 14 19 24
Untuk konfigurasi
4, 6, 8, 10, 12, ....
rumusnya Un = 2n + 2
Sebab
2(1)+2, 2(2)+2, 2(3)+2, 2(4)+2, 2(5)+2
= 2+2, 4+2, 6+2, 8+2, 10+2
= 4 6 8 10 12
Untuk konfigurasi
3, 7, 11, 15, 19, 23, .....
rumusnya Un = 4n - 1
Sebab
4(1)-1, 4(2)-1, 4(3)-1, 4(4)-1, 4(5)-1, 4(6)-1,....
= 4-1, 8-1, 12-1, 16-1, 20-1, 24-1, .....
