what is 2n choose n The symbol is usually read as n choose k because there are ways to choose an unordered subset of k elements from a fixed set of n elements For example there are ways to choose 2 elements from 1 2 3 4 namely 1

On the right side you re choosing n objects from 2n objects On the left side it s equal to n k n n k So divide the 2n objects into 2 groups both of n size Then the total number of way of choosing n objects is partitioning over how many elements you choose from one group and the remaining n k elements from the other group In full generality the binomial theorem tells us what this expansion looks like small begin align a b n C 0a n C 1a n 1 b C 2a n 2 b 2 C nb n end align a b n C 0an C 1an 1b C 2an 2b2 C nbn where C k C k C k is the number of all possible combinations of k

The sequence 4 n 2n n n c eventually decreases if c 1 4 this is straightforward divide the squares of two consecutive terms and subtract 1 and its limit equals 1 Thus for large enough n we get the upper bound 1 n c For c 1 this just works from the very beginning Fedor Petrov Obviously 1 x n 1 x n 1 x 2n On the right the coefficient by x n is 2n choose n On the left it is sum k 0 n n choose k n choose n k In fact with a little change of the language we can prove a more general identity displaystyle sum k ge 0 n choose k m choose k n m choose n
