Mtk kelas 9 plis tentang barisan arimatika

Jawaban:

barisan deret geometri

1/8, 1/4, 1/2, 1 ,2, …., dan seterusnya

a = 1/8 dan r = rasionya = u²/a = 1/4 : 1/8 = 1/4 × 8 = 2

maka, Suku ke 14

Un = ar^(n – 1)

U14 = 1/8. 2^(14-1)

U14 = 1/8. 2^13

U14 = 1/8. 8.192

U14 = 8.192/8

U14 = 1.024 [ C ]
