Question: How many squares are used in Pattern #100?
Answer: If we double the number of white squares along one arm and add one grey square, we will get the total number of squares. Pattern #100 has 100 squares along one arm.
We can use the formula 2 x N +1 where N is the number of squares along one arm or the Pattern number.
This gives us 2 x 100 +1 = 201 squares
