the above limit is infinity and hence does not exist. the reason is that numerator is quadratic and denominator is linear, so after performing polynomial division, you will have 2n+ L1/L2, where L1 and L2 are linear terms. since lim n tends to infinity (n-1)(2n-1)/6n= lim n tends to infinity 2n+lim L1/L2= infinity + some constant= infinity, hence the limit is +infinity which by definition is said to not exist. if u have firther doubts feel free to ask
