I have a question about the solution to this pattern recognition task:
I know that according to the book, the correct answer is E. The "argument" is: Vertical lines represent $1$ integer; horizontal lines represent $5$. The product of the number of lines on each end equals the sum of lines in the middle. But then not only E contradicts this structure, but B as well: the product of the number of lines on each end is $6$, the sum in the middle is $16$.
Any idea what might be the correct answer?
