Final answer:
The value of lim n→ ∞ Sn is undefined.
Step-by-step explanation:
The value of lim n→ ∞ Sn is undefined.
When evaluating the limit of a sequence, we look at the behavior of the sequence as n approaches infinity. If the terms of the sequence approach a specific value or diverge to positive or negative infinity, the limit exists. However, if the terms of the sequence do not converge to a specific value and do not diverge to infinity, the limit is undefined.
In this case, since the limit cannot be determined as n approaches infinity, the value is undefined. Therefore, the correct answer is (d) Undefined.
