Whakaoti mō n
n=\frac{a_{k}-1}{2}
Whakaoti mō a_k
a_{k}=2n+1
Tohaina
Kua tāruatia ki te papatopenga
2n+1=a_{k}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2n=a_{k}-1
Tangohia te 1 mai i ngā taha e rua.
\frac{2n}{2}=\frac{a_{k}-1}{2}
Whakawehea ngā taha e rua ki te 2.
n=\frac{a_{k}-1}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
