Step 1
Step 1: Rewrite the given series as a power series: \(-\sum_{n=1}^{\infty} \frac{1}{n - \frac{1}{2}} = -\sum_{n=1}^{\infty} \frac{1}{n} \cdot 2\) Show more…

Either use the formula for the sum of a geometric series to find the sum, or state that the series diverges. $$ \sum_{n=2}^{\infty} e^{3-2 n} $$
