After using trial and error skills to find out how many cars need to be moved before Ben can drive his car out of the garage, we recorded our results using this table. We then looked for patterns so we could complete the table without having to practically investigate using the resources. Finally, we attempted to find a formula so we can find the ‘nth’ term. As you can see, we have found the formula to find out how many spaces each garage will have.
Can you find a formula to work out how many moves each car park will take?
