Choose the best first step to simplify and calculate the limit

lim_{n \to \infty} \frac{3^{n} + 4^{n - 1}}{3^{n} + 4^{n + 1}}

We divide the numerator and the denominator by

4^{n}

We divide the numerator and denominator by

3^{n}

We substitute

n = \infty

We take

3^{n}

outside the brackets in the numerator and the denominator.

We take

4

outside the brackets in the numerator and the denominator.
