Inspired a bit of GeoGebra tinkering. May be more to come. It’s actually two patterns, one of triangles and one of right trapezoids. If you download the sketch, there's tools to use in the sequence commands.
Very interesting fractions questions. For an NxN square, which fractions are shown? Which fractions repeat? Can you come up with a formula for the fraction at spot (i,j)?
