Evaluate the limit of sequence below: \displaystyle \large{\lim_{n \to \infty} \frac{3}{\sqrt{4n^2+2n}-2n}}
I've been getting 0 as answer. I plotted the graph and it shown that it was approaching 6 when n tends to infinity, but I couldn't figure out how to evaluate the limit like this.
Please show your work on how the answer is 6. Thank you!​
