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