That means they change from left to right in a specific order. The question is if the figures continue to change in the same order what should be the third figure so that the series is completed Study the following problem based on series. Problem Figures Study the position of the dot in all the Problem Figures. Note that it keeps moving around the square in the clockwise direction. Where would it be in the third position If you observe in the second figure the dot is at the upper right corner and in the fourth figure the dot is at the bottom left corner.
