As evening came, Emek and Luna placed lanterns along a forest path while Pixel counted them. The first stop had 3 lanterns, the second had 6, and the third had 9. Pixel saw that the number of lanterns increased by 3 each stop. Together they predicted the next stops would have 12 and 15 lanterns. They finished lighting the path, and travelers walked safely through the forest.
