Find the next term: A\#1, B\$2, C\%3, D\&4, \underline{\hspace{0.5cm}}?
Correct Option
Option A
Explanation
Letters increase alphabetically (A, B, C, D, E), numbers increase by 1 (1, 2, 3, 4, 5), and symbols follow standard US keyboard number row shift symbols (1 \rightarrow !, 2 \rightarrow @, 3 \rightarrow \# or consecutive shift symbols \#, \$, \%, \&, *).
22
What is the missing symbol: +, \times, -, +, \times, -, +, ___?
Correct Option
Option C
Explanation
The 3-symbol sequence +, \times, - repeats indefinitely. Following +, the next symbol is \times.
23
Identify the next group: \Delta\circ, \circ\square, \square\Delta, \Delta\circ, ___?
Correct Option
Option B
Explanation
The pairs cycle systematically: the second shape of each pair becomes the first shape of the next pair (\Delta\circ \rightarrow \circ\square \rightarrow \square\Delta \rightarrow \Delta\circ \rightarrow \circ\square).
24
What replaces the question mark: \le, <, =, >, \ge, ?
Correct Option
Option B
Explanation
The sequence traverses relational comparison operators from lowest to highest order and repeats cyclically, returning to \le.
25
Complete the pattern: \diamondsuit, \heartsuit, \spadesuit, \clubsuit, \diamondsuit, \heartsuit, \underline{\hspace{0.5cm}}?
Correct Option
Option B
Explanation
Standard card suits cycle in order: Diamonds, Hearts, Spades, Clubs. After Hearts, the next suit is Spades (\spadesuit).
26
Find the missing term: \cap, \cup, \cap\cap, \cup\cup, \cap\cap\cap, ___?
Correct Option
Option B
Explanation
Intersection (\cap) and union (\cup) symbols alternate, increasing their count by 1 after every pair. Three intersections are followed by three unions (\cup\cup\cup).
27
What comes next: \rightarrow, \uparrow, \leftarrow, \downarrow, \rightarrow, ___?
Correct Option
Option C
Explanation
The arrow rotates counter-clockwise by 90^\circ: East \rightarrow North \rightarrow West \rightarrow South \rightarrow East \rightarrow North (\uparrow). What comes next in the pattern: *, **, ***, **, *, **, ___?$A)$*$B)$**C) ***D) ****Answer: CExplanation: The number of asterisks oscillates up and down: 1, 2, 3, 2, 1, 2, 3.
28
Complete the sequence: \subset, \subseteq, \supset, \supseteq, \subset, ___?
Correct Option
Option B
Explanation
The set relation symbols follow a repeating 4-element cycle: proper subset (\subset), subset (\subseteq), proper superset (\supset), superset (\supseteq).
29
Find the next term: \oplus, \ominus, \otimes, \oslash, \oplus, \ominus, ___?
Correct Option
Option B
Explanation
Circled arithmetic operators cycle through addition, subtraction, multiplication, and division: \oplus, \ominus, \otimes, \oslash. After \ominus, the next is \otimes.
30
What replaces the blank: \Box, \boxminus, \boxplus, \boxtimes, \Box, ___?
Correct Option
Option B
Explanation
The pattern repeats four box variants: empty, minus, plus, cross. After the empty box, the minus box (\boxminus) follows.
31
What comes next: \vert{}, \vert{}\vert{}, \vert{}\vert{}\vert{}\vert{}, \vert{}\vert{}\vert{}\vert{}\vert{}\vert{}\vert{}\vert{}, ___?
Correct Option
Option C
Explanation
The number of vertical bars doubles each step: 1, 2, 4, 8, 16.
32
Complete the sequence: \bigtriangleup, \bigtriangledown, \bigtriangleup\bigtriangleup, \bigtriangledown\bigtriangledown, \underline{\hspace{0.5cm}}?
Correct Option
Option B
Explanation
Upright triangles alternate with inverted triangles, incrementing the count after each pair: 1 upright, 1 inverted, 2 upright, 2 inverted, followed by 3 upright (\bigtriangleup\bigtriangleup\bigtriangleup).
33
Find the next symbol: \infty, \propto, \infty, \propto, \propto, \infty, \propto, \propto, ___?
Correct Option
Option B
Explanation
The infinity symbol (\infty) alternates with an increasing count of proportionality symbols (\propto): 1, then 2, then 3. Thus, a third \propto is required to complete the group of three.
34
Complete the pattern: \models, \Vdash, \Vvdash, \models, \Vdash, ___?
Correct Option
Option C
Explanation
The turnstile logic symbols cycle through one, two, and three vertical/horizontal stroke combinations in a repeating 3-element pattern.
35
What replaces the question mark: \star, \star\#, \star\#\$, \star\#\$\&, ?
Correct Option
Option A
Explanation
A new symbol is appended to the string at each step, following a consistent progression (\star \rightarrow \# \rightarrow \$ \rightarrow \& \rightarrow \%).
36
Find the missing term: \circ\bullet\circ, \bullet\circ\bullet, \circ\bullet\circ, \underline{\hspace{0.5cm}}?
Correct Option
Option C
Explanation
The pattern strictly alternates between inverted black/white circular triplets: \circ\bullet\circ and \bullet\circ\bullet.
37
What comes next: \angle 45^\circ, \angle 90^\circ, \angle 135^\circ, \angle 180^\circ, ___?
Correct Option
Option B
Explanation
The angle measure increases by an arithmetic progression of +45^\circ at each step (180^\circ + 45^\circ = 225^\circ).
38
Complete the series: \uparrow\uparrow, \uparrow\downarrow, \downarrow\uparrow, \downarrow\downarrow, \uparrow\uparrow, ___?
Correct Option
Option B
Explanation
The pattern represents a 2-bit binary counting cycle where \uparrow = 0 and \downarrow = 1: 00, 01, 10, 11, and then restarts with 00 (\uparrow\uparrow), 01 (\uparrow\downarrow).
39
What is the next symbol: \sim, \approx, \cong, \equiv, ___?
Correct Option
Option C
Explanation
Equivalence relation symbols progress through similarity (\sim), approximation (\approx), congruence (\cong), and identity (\equiv), after which the 4-element cycle restarts with \sim.
40
Find the missing group: \#\#, \#\#\#\#, \#\#\#\#\#\#, ___?
Correct Option
