- Un = a + (n – 1) × b
- a [tex]\to[/tex] suku awal
- b [tex]\to[/tex] beda (suku 2 – suku 1)
☞ Penyelesaian Soal
- 2 [tex]\to[/tex] 4 = +2
- 4 [tex]\to[/tex] 8 = ×2
- 8 [tex]\to[/tex] 10 = +2
- 10 [tex]\to[/tex] 20 = ×2
- 20 [tex]\to[/tex] 22 = +2
- 22 [tex]\to[/tex] 44 = ×2
- 44 [tex]\to[/tex] … = +2
44 + 2 = 46 (suku ke-8)
46 × 2 = 92 (suku ke-9)
92 + 2 = 94 (suku ke-10)
☞ Urutan aritmatika menjadi:
- 2, 4, 8, 10, 20, 22, 44, 46, 92, 94
a. 6+ (10 – 4) = ….
b. 2 + (-13)-8=
c.-15-(-14) – 10 = ….
d. 20 + (-44) + (-10) =
e. -36-(-22) =
