Today in problem solving we solved a question, this is the question:


Tukutuku panels can be made from wooden rods (kaho) with cross stitches (tuinga), often using many colours.
The kaokao is a traditional tukutuku design that symbolises the strength of a warrior.

Imagine you continued this pattern until there were 8 kaho. How many tuinga would there be?
What if there were18 kaho? What if there were 38 kaho?
Find a way to calculate the number of tuinga needed for any number of kaho

 This is one of the ways we figured it out-
