What do you call a repetitious sequence in which the lighting state is altered?

The term used to describe a repetitious sequence in which the lighting state is altered is referred to as a "Chase." This effect is commonly utilized in theatrical productions to create dynamic lighting patterns that enhance the visual experience of a performance. A chase typically involves multiple lights turning on and off or changing colors in a synchronous or asynchronous manner, making the transition visually striking and engaging for the audience.

In contrast, a fade is a smooth transition in lighting intensity, where the light gradually increases or decreases rather than changing in a set sequence. Flash refers to a sudden burst of light, usually for dramatic effect, but does not imply repetition. Pulse involves a rhythmic fluctuation of light levels, often creating a breathing effect but may not necessarily involve distinct, repeating alterations in a defined sequence as seen in a chase.
