**ODDS & EVENS**

**1.** Study the Python code below.

Predict what the output would be.

**2.** Go to cscircles.cemc.uwaterloo.ca/console. Enter and run the Python code from #1. Plot the ** number** and

**values on the grid below. What is the equation of the function plotted?**

*sum*

**3.** Edit the Python code from #1 to list the first 5 even numbers and sums. Sample output shown below.

**4.** Edit the Python code from #3 to list the first 5 natural numbers and sums. Sample output shown below.

**5.** The 3 images below relate to the ideas above. The first image is annotated as an example. Similarly annotate the other 2 images.

- The first 5 odd numbers fit in a 5 x 5 square, and their sum is 25.
- The first N odd numbers fit in a NxN square, and their sum is N
^{2}.
