Solving: multiple choice questions about the definition of sequence limit The convergence of sequence {xn} to real number a is equivalent to () For any given E > 0, a has an infinite number of sequences in (A-E, a + e) For any given E > 0, B has finite multinomial with sequence in (A-E, a + e) For any given E > 0, C has an infinite number of sequences outside (A-E, a + e) For any given E > 0, D has finite multinomial with sequence outside (A-E, a + e) I think it's all infinite. I don't understand, I just don't know why it's d

Choose D
This problem is mainly to understand the definition of sequence convergence
The sequence {xn} converges to the real number a, that is to say, for any E > 0, there is an integer n > 0. When n > N, a-e
