+ + + * * * * + + + + * * * + + + + ? ? *+ *The pattern for + is 3, 4, 5. The pattern for * is 4, 3, 2.
O O X X X X O O X X X O O X X ? ? XO OThe pattern for X is 4, 3, 2, 1. There are always two O symbols.
+ + + & & & & & ; - - - & & & & ; x x x & & & ; ÷ ÷ ÷ & & ; ?+ + + &The pattern is 3+ 5& ; 3- 4& ; 3x 3& ; 3÷ 2& ; and therefore what follows must be 3+ 1&.
* * | o o o o | * * ? | o o ? | * * * * | o o |* oThe pattern for * is 2, 3, 4. The pattern for o is 4, 3, 2. The vertical lines act as separators.
# \$ & # \$ \$ & # # \$ ? & ? # \$ \$ \$ &\$ #With the & symbol acting as a separator, the \$ and # symbols are increased alternately by one.
# + + + - - - # + + - - - # + + - - # + - - # + - # ? ?- #With the # symbol acting as a separator, the + and - symbols are decreased alternately by one.
> < = = + > ? ? = +< =The first five symbols > < = = + repeat as a set.
6 9 + + 9 6 X X 6 9 + + 9 6 X X 6 9 + + ? 6 X ?9 XThe first eight symbols 6 9 + + 9 6 X X repeat as a set.
\$ # # % % % | # % % \$ \$ \$ | ? | \$ # # % % %% \$ \$ # # #With the | symbol acting as a separator, each set consists of six entries (one first entry, two second entries and three third entries).The first, second and third entries are \$ # % in turns.
> = = < < < < < = = > > > = = < < < = = ? > > > > = = ? = => <The pattern for > is 1, 3, 5. The pattern for < is 5, 3, 1.There are = = to act as separators.
@ < ^ > @ ? ^ > @ < ? ? @ < ^ > @ < ^ > @< ^ >The first four symbols @ < ^ > repeat as a set.
! ! o x ! ! ? x ! ! o x ! ! o ? ?o x !The first four symbols ! ! o x repeat as a set.
+ - - X + + + - - - - X + + + ? ? ? - - - - - X+ + -The pattern for + is 1, 3, 5. The pattern for - is 2, 4, 6. The X symbols act as separators.
|| || | X || || X || | X || X ? ?| XThe X symbols act as separators. The number of vertical lines reduce by 1 in each set.
O O O O + O O O - - O O + + + ? - - - -OThe pattern for + is 1, 3. The pattern for - is 2, 4. The pattern for O is 4, 3, 2, 1.
+ - X + + - X + + - - X + + - ? ? XNone of theseThe pattern for (+ - X) triplet is (1, 1, 1), (2, 1, 1),(2, 2, 1), (2, 2, 2). So, the answer is - X.
