Puzzle #16: Bigger With Fewer Sides

Hard · Progression · target time about 27 seconds

Which option completes the pattern?

How to solve it (answer: E)

The rule

In each row, the shape gets one size bigger and loses one side at each step.

Step by step

  1. Look at the top row: a small solid hexagon, then a medium solid pentagon, then a large solid square.
  2. The middle row follows the same step.
  3. The bottom row goes a medium solid hexagon, then a large solid pentagon, so next comes a very large solid square.
  4. Check both rules: only one option fits them both.

Tip: Find what changes by the same amount each step, then check that the amount holds in every row.

Why the wrong options look right

The wrong options keep most of the pattern and change the size or the number of sides, so each one looks finished at a glance. Check both before you choose.
