【题目】A sequence of natural numbers is constructed by listing the first 4, then skipping one, listing the next 5,skipping 2, listing 6, skipping 3, and, on the nth iteration, listing n+3 and skipping n. T he sequence begins 1, 2, 3, 4, 6, 7, 8, 9, 10, 13. What is the...
Clearly 999(1000)2<500,000<1000(1001)2. This means that the number of skipped number "blocks" in the sequence is 999−3=996 because we started counting from 4. Therefore n=996(997)2=496,506, and the answeris 496,506+500000=(A)996,506....

While reading Walter Rudin's Principles of Mathematical Analysis, I ran into the following theorem and proof: Theorem 2.12. Let {En}{En}, n=1,2,…n=1,2,…, be a sequence of countable sets, and put S=⋃n=1∞En.S=⋃n=1∞En. Then SS is countable. Proof. Let every s...

(published no later than 2011). To facilitate research on citation dynamics across different fields48, we have also used the same procedure to fit the citation sequences for papers that have received at least 10 citations within 10 years across all fields of study from the 1960s to the ...
Microbial breakdown of organic matter is one of the most important processes on Earth, yet the controls of decomposition are poorly understood. Here we track 36 terrestrial human cadavers in three locations and show that a phylogenetically distinct, inte
