Cauchy sequence, an Uncommon card
In mathematics, a Cauchy sequence is a sequence whose elements become arbitrarily close to each other as the sequence progresses.
- Rarity
- Uncommon
- Domain
- Science
- ATK
- 65
- DEF
- 35
- Power
- 100
- Wikipedia reads a year
- 78,000
Power 100 (ATK + DEF): stronger than 55 % of WikiCards cards.
Cauchy sequence quiz: 3 questions
Three questions on the Cauchy sequence card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
It is not sufficient for each term to become arbitrarily close to the ______ term.
Answer
preceding. It is not sufficient for each term to become arbitrarily close to the preceding term. From the Cauchy sequence article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Cauchy sequence. Cauchy sequence 65 · Bortle scale 60 · Elias G. Brown 57 · Amsler grid 54 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Bortle scale. Bortle scale 140,000 · Boltzmann distribution 100,000 · Cauchy sequence 78,000 · Elias G. Brown 140 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- More precisely, given any small positive distance, all excluding a finite number of elements of the sequence are less than that given distance from each other.
- Cauchy sequences are named after Augustin-Louis Cauchy, they may occasionally be known as fundamental sequences.
- It is not sufficient for each term to become arbitrarily close to the preceding term.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cauchy sequence article was read about 78,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 35: each hit it takes is cut by 14 %.
How to get Cauchy sequence
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
