hey i'm truly sorry if this isnt in the right forum, i actually couldnt find a subforum that addressed sequence problems

so this is a basic problem inolving factorials so don't make the answer too complicated please

show that (2n)!/n! = 2^n (1x3x5...x(2n -1))

i really have very little work to show cos i got nowhere in the hours i've been trying to wrap my head around this. its probably simple and i'm overestimating it but the farthest i've got is to 2n x (2n-1) x (2n-2) x (2n-3) x...x (n)

i'm not even sure that is correct

any help would be appreciated, please show all working and details, i'd like to totally understand this
