Anei tētahi huinga tau: {6, 8, 3, 11, 7}

Ko te 7 te tau waenga.

Mēnā he taurua te maha o ngā raraunga, ka tātaihia te toharite o ngā tau waenga e rua. Hei tauira: Hei kimi i te tau waenga o tēnei huinga tau: {5, 8, 2, 10, 3, 11, 15, 4}

  1. Raupapahia i te tuatahi: {2, 3, 4, 5, 8, 10, 11, 15}
  2. Tohua ngā tau o waenganui: {2, 3, 4, 5, 8, 10, 11, 15}
  3. Tātaihia te toharite o ēnei tau e rua: 5 + 8/2 = 13/2 = 6.5

No reira, ko te 6.5 te tau waenga o tēnei huinga tau.
