Answer:
a. A sequence {sn}1[infinity] converges to s means that the sequence {sn}1[infinity] gets arbitrarily close to the value s as the index n increases without bound. In other words, the sequence converges to s as n approaches infinity.
To understand this concept, imagine a series of dots on a number line, each representing a term of the sequence. As n gets larger, the dots get closer and closer to each other, eventually forming a single point at s. This means that the sequence converges to s as n approaches infinity.
