Penjelasan dengan langkah-langkah:
Diketahui :
U3=256
U6=32
kita cari dulu rasio nya
r³=U6/U3
r³=32/256
r³=1/8
r=1/2
kita cari dulu a/U1
U1=U3:r²
U1=256:1/2²
U1=256:1/4
U1=1.024
lalu kita cari U8
u8 = a x r^7
u8 = 1.024 x 1/2^7
u8 = 1.024 x 1/128
u8 = 8
u3 = 256
u6 = 32
u6/u3 = (a x r^6 - 1)/(a x r^3 - 1)
32/256 = r^5/r^2
1/8 = r^3
(1/2)^3 = r^3
r = 1/2
u3 = a x r^2
256 = a x (1/2)^2
a = 256 x 4
a = 1.024
u8
= a x r^8 - 1
= a x r^7
= 1.024 x (1/2)^7
= 8
