Cara : memasukkan nilai n
1. Un = 3n – 4
n mulai dari 1 – 5
U1 = 3-4 = -1
U2 = 6-4 = 2
U3 = 9-4 = 5
U4 = 12-4 = 8
U5 = 15-4 = 11
= -1,2,5,8,11,… (C)

2. Un = $frac{n}{n+2}$
n mulai 1-3
U1 = $frac{1}{3}$
U2 = $frac{2}{4}$
U3 = $frac{3}{5}$
= $frac{1}{3}, frac{2}{4}, frac{3}{5},...$ (C)

Semoga membantu 🙂
