How to prove that 1/2 can't be the limit of the sequence {(3n-2)/(4n+1)} ?

I have tried prove this by the negation of the definition that is there exist an epsilon for all n_{0 }belongs to positive integers such that n> n_{0 }implies |(3n-2)/(4n+1)-1/2| >= epsilon.

But the problem is could not find an epsilon such that |(3n-2)/(4n+1)-1/2| is greater than or equal to that epsilon.

Any help would be great..
