Answer:
It will be a rectangle with the short side turned vertically (just like the 2nd figure).
Step-by-step explanation:
Every 3rd figure in this pattern is a rectangle with the long side turned vertically. This means all multiples of 3 will be this way: 3, 6, 9, 12, 15.
This means the figure before the 15th figure, the 14th figure, will be the same as the second figure; that is, a rectangle with the short side turned vertically.
