In each subsequent figure, one new disign is added infront of the pre-existing designs and behind the pre-existing designs alternately. Pre-existing designs move two & half steps in anticlockwise direction and interchange positions. From Problem Figure (B) to (C), all the three designs move two & half steps in anticlockwise direction and the first and the third designs interchange positions and a new design is added behind the pre-existing designs. From Problem Figure (C) to (D), all the designs move one & half steps in anticlockwise direction and the first and the fourth designs interchange positions and so as the two middle designs (i.e, the second and the third designs). A new design is added in front of the pre-existing designs. Thus, from Problem Figure (D) to Answer Figure, all the designs would move half-step in anticlockwise direction and the first and sixth designs would interchange positions and so as the second and the fifth designs and the third and the fourth designs. A new designs would be added in front of the pre-existing designs.
