Nomor 4
b = (U8 - U3) / (8 - 3)
= (27 - 7) / 5
= 20 / 5
= 4
U20 = U8 + (20 - 8)b
= 27 + 12(4)
= 27 + 48
= 75
jawaban C
Nomor 5
U2 + U4 = 26
a + b + a + 3b = 26
2a + 4b = 26
a + 2b = 13
U8 - U5 = 9
a + 7b - (a + 4b) = 9
3b = 9
b = 3
a = 13 - 2(3)
= 13 - 6
= 7
U10 = a + 9b
= 7 + 9(3)
= 7 + 27
= 34
jawaban D
Nomor 6
U4 + U6 = 28
a + 3b + a + 5b = 28
2a + 8b = 28
a + 4b = 14
u2 = a + b
5 = a + b
a = 5 - b
5 - b + 4b = 14
3b = 14 - 5
b = 9 ÷ 3
= 5 - 3
= 2
U9 = a + 8b
= 2 + 8(3)
= 2 + 24
= 26
jawaban B
