Answer:
The black triangle
Step-by-step explanation:
We can start by noticing that the pattern is repeating every five shapes.
So we know that The shape given every number divisible by 5 is going to be the white circle.
So the 5th shape, 10th shape, and 105th shape are examples of times there will be a white circle.
We can now see that 214 is almost divisible by 5, but -1. Let's imagine the number is 215 for a second. Then the position would be the white circle. Now what's right before the white circle? The black triangle.
The black triangle is in the position.
