In the 1870s, several years after the end of the Civil War, veteran Jeb McAllister and his wife Hattie struggle to raise their adolescent son Will and infant daughter in the wilds of Montana. [6]
The lazy caterer's sequence (green) and other OEIS sequences in Bernoulli's triangle. As the third column of Bernoulli's triangle (k = 2) is a triangular number plus one, it forms the lazy caterer's sequence for n cuts, where n ≥ 2. The sequence can be alternatively derived from the sum of up to the first 3 terms of each row of Pascal's ...
1 is read off as "one 1" or 11. 11 is read off as "two 1s" or 21. 21 is read off as "one 2, one 1" or 1211. 1211 is read off as "one 1, one 2, two 1s" or 111221. 111221 is read off as "three 1s, two 2s, one 1" or 312211. The look-and-say sequence was analyzed by John Conway [1] after he was introduced to it by one of his students at a party. [2 ...
The On-Line Encyclopedia of Integer Sequences ( OEIS) is an online database of integer sequences. It was created and maintained by Neil Sloane while researching at AT&T Labs. He transferred the intellectual property and hosting of the OEIS to the OEIS Foundation in 2009. [ 4] Sloane is the chairman of the OEIS Foundation.
Lucas number. The Lucas spiral, made with quarter- arcs, is a good approximation of the golden spiral when its terms are large. However, when its terms become very small, the arc's radius decreases rapidly from 3 to 1 then increases from 1 to 2. The Lucas sequence is an integer sequence named after the mathematician François Édouard Anatole ...
The original music video, now taken down by Youtube, contained footage of the attacks. The song was released on 9/11 of 2012, its music video on 9/11 of 2015, and was brought back to streaming sites 9/11 of 2021 after being taken down in August of that year.

In mathematics, the Jacobsthal numbers are an integer sequence named after the German mathematician Ernst Jacobsthal.Like the related Fibonacci numbers, they are a specific type of Lucas sequence (,) for which P = 1, and Q = −2 [1] —and are defined by a similar recurrence relation: in simple terms, the sequence starts with 0 and 1, then each following number is found by adding the number ...
0 2 + 3 2 + 5 2 + 6 2 = 1 2 + 2 2 + 4 2 + 7 2. The condition requiring that N be a multiple of 2 k +1 is not strictly necessary: there are some further cases for which a solution exists. However, it guarantees a stronger property: if the condition is satisfied, then the set of k th powers of any set of N numbers in arithmetic progression can be ...
