Bab : Barisan dan Deret Bilangan
=============================

→ U2 = 6

→ U7 = 192

Ditanya rasio barisan

Jawaban :
=========

U2 = 6

ar = 6........ (1)

[tex]u7 = 192 \\ {ar}^{(7 - 1)} = 192 \\ {ar}^{6} = 192 \\ ar \times {r}^{5} = 192 \\ 6 \times {r}^{5} = 192 \\ {r}^{5} = \frac{192}{6} \\ {r}^{5} = 32 \\ r = \sqrt[5]{32} \\ r = 2[/tex]
