Question
Evaluate the sums.$$\text { a. } sum_{k=1}^{n}\left(\frac{1}{n}+2 n\right) \quad \text { b. } \sum_{k=1}^{n} \frac{c}{n} \quad \text { c. } \sum_{k=1}^{n} \frac{k}{n^{2}}$$
Step 1
Therefore, we can treat the summand as a constant and multiply it by the number of terms, which is $n$. This gives us $$ \sum_{k=1}^{n}\left(\frac{1}{n}+2 n\right) = n\left(\frac{1}{n}+2 n\right). $$ Show more…
