8=567=426=305=203=?
\(3=6\)In this case, the pattern is the number, in this case, 3, multiplied by the number below it.See?\(8\times7=56\\7\times6=42\\6\times5=30\\5\times4=20\\3\times2=6\)Hope this helped :)
\(8\rightarrow56=8\cdot7\\7\rightarrow42=7\cdot6\\6\rightarrow30=6\cdot5\\5\rightarrow20=5\cdot4\\\\4\rightarrow12=4\cdot3\\\\3\rightarrow6=3\cdot2\\\\Ans.\ 3\rightarrow6\)
