When n identical resistance are connected in series , Req=nR , Req value is greater than the maximum value of resistance in combination.
For n identical resistance are connected in parallel , Request=R/n , Req is smaller than the minimum value of resistance in combination.
now,
Rmax/Rmin =nR/R/n
= n^2
