select_next_figure_increasing_size_sequence
GitHub
Prompt
The scene has two separated areas: a top SEQUENCE area and a bottom CHOICES area. In the SEQUENCE area, the shapes are the same shape and the same color, and their sizes strictly increase from left to right. First identify the constant size step between consecutive sequence shapes, then select the one correct option (out of 4) in the CHOICES area that continues the same shape, color, and size-increase pattern. Circle the correct option and show the full process step by step.
