Tollong dijawab pertanyaan ini

aduh banyak amat, sy jawab yg C aja ya
a = 3/4
r = U₂/U₁ = (3/2)/(3/4)
r = 3/2 x 4/3
r = 2

[tex] U_{n} = ar^{n - 1} [/tex]

[tex] U_{n} = \frac{3}{4} ( 2)^{n - 1} [/tex]

[tex] U_{n} = \frac{3}{4} \frac{ 2^{n}}{2} [/tex]

[tex] U_{n} = \frac{3}{8} 2^{n} [/tex]

a.) 3, 9, 27, 81, 243, 729, ... (tinggal dikali sama 3 semua)
b.)1/2, 1/6, 1/18, 1/54, 1/162, 1/486, ... (dikali 1/3)

smoga membantu
