As evening approached, Emek and Luna hurried to light the forest trail. The first section needed 5 lanterns, the second needed 8, and the third needed 11. Emek noticed that each new section needed 3 more lanterns than the one before. Using the pattern, Luna found that the fourth section needed 14 lanterns and the fifth needed 17. They prepared the correct number for each section, and soon the whole route glowed safely through the trees.
