Which Symbol Comes Next in the Sequence?

Official explanation

Official Community Explanations First of all, I would like to sincerely thank everyone who took the time to solve this puzzle and share their reasoning. We received many excellent explanations, often approaching the same pattern from different perspectives. Among all the submissions, we selected the following three explanations from the Reddit community for standing out with their clarity, originality and completeness. ⸻ 1. lemasney F is the answer. In each line, a 3 step sequence establishes the pattern: all three vertical lines in each step are being reduced/removed/downsized by one unit or segment. If you were to assign numbers to the horizontal lines to establish numerical values, the first line would be 3-3-2, 2-2-1, 1-1-0. The last line would be 1-2-3, 0-1-2, and 0-0-1. F represents 0-0-1. Why we selected this This explanation stood out because it goes beyond simply identifying the visual pattern. By assigning numerical values to each bar, it transforms the puzzle into a clear mathematical progression. It demonstrates not only what changes between each step, but also why the correct answer must be F, making it one of the most complete explanations submitted. ⸻ 2. Life-Ambassador-5993 F - they all drop one in height and then drop one in height again. There is also a pattern in the columns - the left bar drops 2 in height then the middle and right bar drop one in height each, then the right bar increases 2 in height. Why we selected this Most people identified the one-step reduction in the bars, but this explanation goes further by discovering a second, independent pattern across the columns. Showing that multiple observations lead to the same answer makes this explanation particularly insightful and demonstrates a deeper analysis of the puzzle. ⸻ 3. gerhard1953 Solution: F. Reason: In each row 1) the right figure always has one less bar than the middle figure and 2) the shortest bar is always in a different position. Why we selected this This explanation approaches the puzzle from a different perspective by comparing the figures within each row rather than tracking the entire sequence. It identifies two simple rules that consistently hold throughout the puzzle, providing a concise yet effective justification for why F is the correct answer.
