I'm having difficulty with another quiz.
By the way, thanks to everyone who answered my previous question or who wants to think over it :)
What letters should I put in place of the question mark?
A B C ? ? ? C A D B B D A C B A D B C A D
C B D
using the fourth row, we use two letters to get the upper one using examples from other places in the triangle.
from the fourth row we have
C A, to obtain the question mark above them we look for other instance in the triangle that has C A and look above it. In this case, the last row. We can also verify that since
C Bgives a
B, (example from the last two columns in the 5th row).
