Using Geometry by Expression tool to make set of lines in QGIS

I am using QGIS 3.x.

I am trying to make a set of lines that are 50m to 2000m, at 50 meter intervals (eg: line 1 is 50m, line 2 is 100m, line 3 is 150m, etc).

I did it manually using the Advanced digitizing tool bar, but I would like to learn to do it more elegantly using the Geometry by Expression tool.

How do I use the “Geometry by Expression” tool to make a set of lines with a particular length interval using QGIS 3.x?
