I could use some help with my proving. The assignment goes as follows:
"Prove with mathematical induction that
((n+1)(n+2)...(2n)) / 22
is a whole number with all values of n"
I know the basic principle of induction but I can't see how can I show the "n+1" -step.
Please excuse my inaccurate expressions, my native language is finnish I would REALLY appreciate the help!
