SUMMARY
The sequence defined by an = (n!)/(2n! + 1) converges to 0 as n approaches infinity. The reasoning involves comparing the growth rates of the numerator and denominator, where both factorials grow similarly, leading to the conclusion that the limit exists. By applying the squeeze theorem, if 0 ≤ an ≤ bn for a suitable bn that converges, then an must also converge. This formal approach confirms the intuitive expectation of convergence.
