Tiga suku selanjutnya dari barisan geometri -1, 4, -16, ... adalah​

64, -256, 1.024

Penjelasan dengan langkah-langkah:

-1, 4, -16, 64, -256, 1.024

x-4 x-4

r = -4

bilangan selanjutnya

U4 = -16 x (-4) = 64

U5 = 64 x (-4) = -256

U6 = -256 x (-4) = 1.024

[tex] - 1,4 , - 16,... \\ a = - 1 \\ r = \frac{ 4}{ - 1} = - 4 \\ un = a {r}^{n - 1} \\ u4 = ( - 1)( - 4) {}^{ 4 - 1} = 64 \\ u5 = ( - 1)( - 4) {}^{5 - 1} = - 256 \\ u6 = ( - 1)( - 4) {}^{6 - 1} = 1.024[/tex]
