Diketehu barisan geometri dengan u4=40 dan u6=160 Tentukan suku ke 6

Jawaban:

U4 = 40

U6 = 160

U4 = 40

ar³ = 40

U6 = 160

ar^5 = 160

(ar³)r^2 = 160

(40)r^2 = 160

r^2 = 160/40

r^2 = 4

r = √4

r = 2

r = 2 disubtitusikan ke persamaan ar³ = 40

ar³ = 40

a (2)³ = 40

a × 8 = 40

a = 40/8

a = 5
