Give the rule for the total number of toothpicks that Sarah would need if she was to continue following the pattern and complete ‘n’ designs.
Use this rule to find the total number of toothpicks needed to complete the first 12 designs using Sarah’s pattern.
Hints: I already know the equation for the nth design is 4n+1=t. But, the question is asking for the total equation.
