Which option completes the visible spectrum by increasing wavelength sequence gap at position 4, directly after green and directly before orange?

Answer options

• Option: green
  "green" vs. "yellow" Green is position 3 and the direct; misses the target mapping. green stays inside the closed sequence visible spectrum by increasing wavelength. The task targets this mapping, so green remains wrong in this prompt.
• Option: orange
  "orange" vs. "yellow" Orange is position 5 and the direct; misses the target mapping. orange stays inside the closed sequence visible spectrum by increasing wavelength. The task targets this mapping, so orange remains wrong in this prompt.
• Option: blue
  "blue" vs. "yellow" Blue is position 2 in the visible; misses the target mapping. blue stays inside the closed sequence visible spectrum by increasing wavelength. The task targets this mapping, so blue remains wrong in this prompt.
• Correct: yellow
  "yellow" - target Yellow is position 4 in the visible spectrum, directly after. yellow stays inside the closed sequence visible spectrum by increasing wavelength. The task targets this mapping, and yellow remains correct in this prompt.

Solution

yellow

yellow is correct: in visible spectrum by increasing wavelength, position 4 sits between green and orange; the position and neighbor claims make the gap unique. The prompt targets yellow, so the graph keeps this mapping stable against close alternatives. Source: Wikidata. As of: 2026-02-13.

Fun fact

sequence_completion requires sequence id, missing position, predecessor, and successor so ordering is not guessed from labels. yellow stays anchored with additional dataset context. The graph therefore uses a multi-hop graph path;
