Size Progression
Size Progression problems feature figures that change in size (increase or decrease) following a consistent pattern. The progression can be arithmetic (adding constant each step) or geometric (multiplying by constant ratio). You must identify the size pattern and determine the next figure's dimensions.

Prerequisites
How to Solve Size Progression Problems
Step 1: Measure or note the size (radius, side length, area) of each figure
Step 2: Calculate the difference between consecutive sizes
Step 3: If differences are constant → arithmetic progression
Step 4: If ratios between consecutive sizes are constant → geometric progression
Step 5: Apply the same change to the last figure's size
Step 6: The shape type usually remains constant; only size changes
Step 7: Select the figure with the calculated size
Example Problem
Example: Circle radii: 10, 20, 30, 40. What is the next radius? Solution: Step 1: Radii: 10, 20, 30, 40 Step 2: Differences: +10 each time Step 3: Next radius = 40 + 10 = 50 Answer: Circle with radius 50
