Gak tau gimana ngejelasin rumusnya :D ngarang inimah :)
3x2 = 6
(6x2)-1 = 11
(11x2)-2 = 20
(20x2)-3 = 37
(37x2)-4 = 70
(70x2)-5 = 135
(135x2)-6 = 264
(264x2)-7 = 521



:D mungkin rumusnya "X= (nx2)-urutan n -1"
1 3 1

U2 - U1 = 6-3 = 3 -> 3 - 0
U3 - U2 = 11-6 = 5 -> 6 - 1
U4 - U3 = 20-11 = 9 -> 11 - 2
U5 - U4 = 37-20 = 17 -> 20 - 3
U6 - U5 = n-37 = m -> 37 - 4 = 33 = m
Jadi, U6= 37 + 33 = 70.
