Question

Lak kalau kayak gini bagai mana jalan ny

Answer 1

1)rumus un nya adalah: Un=6n–3

jadi suku n ke 10= Un=6n–3

U10=6.10–3

=60–3=57

gak bisa bilang rumusnya soalnya klo rumusnya tuh kacau,gak bisa di tulis di sini

mohon perhatiannya!

Answer 2

aritmatika

a = 3

b = U2 - U1 = 9-3 = 6

Un = a + (n-1) b

= 3 + (n-1) 6

= 3 + 6n - 6

= 6n - 3

U10 = 6n - 3

= 6(10) - 3

= 60 - 3

= 57

Geometri

a = 3

r = U2 / U1

= 6 / 3 = 2

Un = ar^(n-1)

= 3 × 2^(n-1)

= 3 × 2^n/2¹

U10 = 3 × 2^n/2¹

= 3 × 2^(10)/2

= 3 × 1024/2

= 3 × 512

= 1536

semoga membantu
