Whakareatia te 1 ki te 3, ka 3. Whakareatia te 3 ki te 5, ka 15. Whakareatia te 5 ki te 7, ka 35. Whakareatia te 35 ki te 37, ka 1295.

$$3+15+35+1295+\frac{37\times 39}{39}\times 41$$

Tāpirihia te 3 ki te 15, ka 18.

$$18+35+1295+\frac{37\times 39}{39}\times 41$$

Tāpirihia te 18 ki te 35, ka 53.

$$53+1295+\frac{37\times 39}{39}\times 41$$

Tāpirihia te 53 ki te 1295, ka 1348.
