To determine whether the sequence (a_n = \frac{2^n + 3^n}{2^n - 3^n}) converges, we analyze the behavior as (n) approaches infinity.

When (n) approaches infinity, the term (3^n) dominates the sequence because it grows much faster than (2^n). Consequently, the term (3^n) dominates both the numerator and the denominator. Thus, the sequence behaves as (\frac{3^n}{3^n} = 1) as (n) approaches infinity.

Therefore, the sequence converges, and its limit as (n) approaches infinity is (1).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
