SAIA KAMBEK UwU
A. 2,4,6
Un = a + (n - 1)b
a = 2
b = 2
n = 5
U5 = 2 + (5 - 1)2
U5 = 2 + (4)2
U5 = 2 + 8
U5 = 10
B. 1,3,5
Un = a + (n - 1)b
a = 1
b = 2
n = 5
U5 = 1 + (5 - 1)2
U5 = 1 + (4)2
U5 = 1 + 8
U5 = 9
C. 2,5,8
Un = a + (n - 1)b
a = 2
b = 3
n = 5
U5 = 2 + (5 - 1)3
U5 = 2 + (4)3
U5 = 2 + 12
U5 = 14

Jawaban:
U5 = 2 + (5 - 1) 2
= 2 + 4 × 2
= 2 + 8
= 10
U5 = 1 + (5 - 1)2
= 1 + 4 × 2
= 5 + 2
= 7
U5 = 2 + (5 - 1) 3
= 2 + (4 × 3)
= 2 + 12
= 14
