The next figure (indicated by ‘?’) in the sequence is

Track each marker separately. The circle stays in column 1 and steps down one row per frame: row 3 → row 4 → row 1 (wrapping to the top after the bottom), so next it must be in row 2, column 1. The triangle stays in column 3 and also steps down one row per frame: row 1 → row 2 → row 3, so next it must be in row 4, column 3. The required figure therefore has the circle in the second row of the first column and the triangle in the bottom row of the third column.
