Take n=5 for example, then above equation becomes 5/6*6/7*7/8*8/9*9/10=5/10.
Which implies all the term cancel except first numerator and last denominator, so in general 5/n+5
is the answer.

The answer is zero because expression is (1-1/6)(1-1/7)........ 1-1=0 and 1-1/6=0 so (1-1/6)*(1-1/7).....=0
