Kamila's triangle of odd numbers
Discrete Mathematics
Level
2
Kamilla constructs the following triangle of positive odd numbers:
\[ \begin{array} { l l l l l } 1 \\ 3 & 5 \\ 7 & 9 & 11 \\ 13 & 15 & 17 & 19 \\ \end{array} \]
On which row will the number 2013 appear?
This problem is shared by Kamilla L.
Details and assumptions
The pattern of the triangle is that there are \(n\) numbers in the \(n\)th row and that each entry is 2 more than the previous value.
The numbers \(13, 15, 17\) and 19 appear in the 4th row.
