rasio = 3
untuk mengetahui suku ke 8. masukkan ke rumus suku ke -n =
U₈ =
2. a = 75
r =
Masukkan rumus suku ke n =
Un =
3.a= 64
r =
Masukkkan ke rumus suku ke n =
Un =
4. Un =-->masukkan n =1 - n=5
U₁ =
U₂ =
U₃ =
U₄ =
U₅ =
5. diketahui suku pertama = 5
suku ke 7 = U₇ = 320
Masukkan ke persamaan U₇
U₇ =
U₇ =
320 = 5 r⁶
= r⁶ --> tanda berubah jadi bagi krn pindah ruas
64 = r⁶
2 = r
jadi rasio barisannya = 2
