Jadi beda = - 1/30
Un = a + (n-1)b
= 1/5 + (n-1)(-1/30)
= 1/5 - 1/30n + 1/30
= - 1/30n + 1/5 + 1/30
= - 1/30n + 6/30 + 1/30
= - 1/30n + 7/30
Bukti
U2 = - 1/30 (2) + 7/30
= - 2/30 + 7/30
= 5/30
= 1/6
Kalau menurutku sih kyk giru caranya
Tapi klo harus milih yg di abcd, aku milih yg A bisa dibuktikan sendiri
Un = 1/n+4
U1 = 1/1+4 = 1/5
Maaf klo salah
