Question수렴하는 수열을 고르세요: ᄀ. $\left\{\frac{1}{2 n+1}\right\}$, ㄴ. $\left\{\frac{(-1)^{n}}{n}\right\}$, ᄃ. $\left\{(-1)^{n}+2\right\}$.

Studdy Solution
From the above analysis, we can conclude that the sequences $\left\{\frac{1}{2 n+1}\right\}$ and $\left\{\frac{(-1)^{n}}{n}\right\}$ are convergent, while the sequence $\left\{(-1)^{n}+2\right\}$ is not convergent.
Therefore, the correct answer is (3) ᄀ, ᄂ.
