On my number line, it shows the area for numbers from 1 - 25.
Not every square was a perfect square so I outlined the perfect squares in picture.
Some patterns I found out about the number line is that the amount of numbers between each perfect square is always even.
eg. 1 [2 3] 4 [5 6 7 8] 9
I also figured out that the amount of numbers until each perfect square is always odd.
eg. 1 [2 3 4] 5 6 7 8 9]
*purple = perfect square
Thanks for reading my post!
Sorry that it doesn't look the best.
