Rasio (r) = 2

Suku pertama (a) = 1/8

[tex]un = a \times {r}^{n - 1} [/tex]

[tex] u(10) \: = \frac{1}{8} \times {2}^{10 - 1} [/tex]

[tex] = \frac{1}{8} \times {2}^{9} [/tex]

[tex] = \frac{1}{8} \times 512[/tex]

• U3 = 1/4 × 2 = 1/2
• U4 = 1/2 × 2 = 1
• U5 = 1 × 2= 2
• U6 = 2 × 2= 4
• U7 = 4 × 2 = 8
• U8 = 8 × 2 = 16
