Whakaoti mō n
n=\frac{a_{n}-4}{3}
Whakaoti mō a_n
a_{n}=3n+4
Tohaina
Kua tāruatia ki te papatopenga
3n=a_{n}-4
Tangohia te 4 mai i ngā taha e rua.
\frac{3n}{3}=\frac{a_{n}-4}{3}
Whakawehea ngā taha e rua ki te 3.
n=\frac{a_{n}-4}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
a_{n}=3n+4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
