Fibonacci achievement

This is a proposal made on 2015-11-15. Please leave comments and suggestions on Talk:Fibonacci achievement, indicating your thoughts on the proposal, including:

• Support - you think this proposal should be added with zero or minor changes
• Do not oppose - you think it's boring/meh/not for you, but it wouldn't harm to have it created
• Oppose - you have a specific reason as to why this ribbon should not exist (state this reasoning in your comment)
• Needs work - you think the achievement should be created after more significant changes have been made

See Proposed achievements for more information on this process.

You go on N expeditions or reach N coordinates where N is a Fibonacci number, celebrating the golden ratio and making a tribute to xkcd.

The Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones.

How the counting works...

• F₀: 0 expeditions, you automatically reach this level before geohashing.
• F₁: 1 expedition, claim this for your first expedition.
• F₂: Also 1 expedition, you should claim the above instead.
• F₃: 2 expeditions, claim this for your second expedition.
• F₄: 3 expeditions.
• F₅: 5 expeditions.
• F₆: 8 expeditions.
• F₇: 13 expeditions.
• ...
• F₁₀: 55 expeditions.
• ...
• F₁₅: 610 expeditions.

A possible integration of this concept to the Two to the N achievement is demonstrated in the talk page. Due to the similarities between this proposed achievement and the existing Two to the N achievement, adding this achievement as a feature of the Two to the N achievement seems most logical.
