Suzie has made a conjecture that the sum of consecutive odd numbers is always a perfect square. The example she used to show this to Timmy is 1 +3 + 5 +7 = 16 = 4^2. However, Timmy was not convinced and made a Venn diagram to find a counter example. Do you agree with Suzie's conjecture? Use evidence from the Venn diagram to support your response.
