Probably the intended ellipse is the one with equation
We can parameterize

Ex 1
the number from 1 to 100, I'll call it x
= (((x + 11) * 6 - 3) / 3 + 5) / 2 - x
= ((6x + 66 - 3) / 3 + 5) / 2 - x
= ((6x + 63) / 3 + 5) / 2 - x
= (2x + 21 + 5) / 2 - x
= (2x + 26) / 2 - x
= x + 13 - x
= 13
finally geez
