Question
**Write the sum using sigma notation.**

\[1^2 + 2^2 + 3^2 + \ldots + 14^2\]

In the diagram, the sigma (\(\Sigma\)) notation is presented to express a series of squaring numbers starting from 1 to 14. 

Explanation:

- The expression \(k = 1\) at the bottom indicates the starting index of the series.
- The upper box is left blank, indicating where the upper limit of the summation should be placed, which in this case is 14.
- The formula for the series inside the sigma notation should be \(k^2\), indicating each term in the series is squared. 

Thus, the series can be written in sigma notation as:

\[
\sum_{k=1}^{14} k^2
\]
