Arithmetic or geometric?

Which of the groups of numbers represent the first few terms of an arithmetic sequence, which represent the first few terms of a geometric sequence? The two fields at the bottom may be moved by mouse dragging. The "Reset" button restores the original situation, the fields being placed at random positions. Below the puzzle, you may activate an evaluation in terms of number of points achieved.
