Let's see some graphs that can be approached to the values proposed by the sequence:
This is an absolute value graph, but the one that most closely approximates the values given in the sequence is:
This was done by plotting points with coordinates taking x as the position in the and sequence and y as the number of points in a position.
Position 1, 2 points.
Position 2, 4 points.
Position 3, 6 points.
Position 4, 4 points.
Position 5, 2 points.
The graph that is given when joining these points is an absolute value graph to which some modifications were made, as for example in the first image.
