at n = 1, [1+\ 1/n\ , 2(3-1/n)]  \varepsilon [2,4]

at n=2, [1+\ 1/n\ , 2(3-1/n)] \varepsilon [3/2,5]

 

as we can see 1+1/n <  2, n\varepsilon positive integers and 3-1/n >2.

 

so the intersection in which this range lies is at minimum range of [1+\ 1/n\ , 2(3-1/n)] which is at  n = 1.

 

if you ask me about union it will be at n->\infty , which is (1,6)
