Question 1

Find the missing number: 3 : 12 :: 3 : ?
The relationship is double factorial. 2 × 3! = 12, 2 × 3! = 12
factorial, advanced

Question 2

Find the missing number: 5 : 240 :: 4 : ?
The relationship is double factorial. 2 × 5! = 240, 2 × 4! = 48
factorial, advanced

Question 3

Find the missing number: 4 : 24 :: 3 : ?
The relationship is factorial. 4! = 24, 3! = 6
factorial, advanced

Question 4

Find the missing number: 5 : 25 :: 2 : ?
The relationship is squaring the number. So 5² = 25, and 2² = 4
square, power

Question 5

Find the missing number: 4 : 12 :: 4 : ?
The relationship is partial factorial (first 2 terms). For 4: 4 × 3 × ... = 12
factorial, advanced

Question 6

Find the missing number: 6 : 9 :: 5 : ?
The relationship is adding 3 (or double for some patterns). Here 5 + 6 = 11
addition, basic

Question 7

Find the missing number: 78 : 9 :: 39 : ?
The relationship is the difference between number and its reverse. |39 - 93| = 54
reverse, digits

Question 8

Find the missing number: 11 : 7 :: 37 : ?
The relationship is the previous prime number. Previous prime before 37 is 31
prime, advanced

Question 9

Find the missing number: 2, 2, 2 : 6 :: 2, 2, 4 : ?
Tribonacci pattern: each term is sum of previous three. 2+2+4 = 8
pattern, sequence

Question 10

Find the missing number: 3 : 27 :: 4 : ?
The relationship is cubing the number. So 3³ = 27, and 4³ = 64
square, power

Question 11

Find the missing number: 7 : 19 (n=4) :: 3 : ?
The nth term formula: a + (n-1)d. For 3, term 4 = 15
progression, sequence

Question 12

Find the missing number: 5 : 7 :: 29 : ?
The relationship is the next prime number. Next prime after 29 is 31
prime, advanced

Question 13

Find the missing number: 35 : 28 :: 25 : ?
The subtractor alternates: -7 then -6. So 25 - 6 = 19
subtraction, basic

Question 14

Find the missing number: 2 : sum of 2 terms = 8 :: 3 : sum of 2 terms = ?
Sum of 2 terms of AP: n/2 × (2a + (n-1)d). For 3, sum = 10
progression, sequence

Question 15

Find the missing number: 3, 4 : 7 :: 3, 2 : ?
Fibonacci pattern: each term is sum of previous two. 3 + 2 = 5
pattern, sequence

Question 16

Find the missing number: 8 : 32 :: 7 : ?
The relationship is multiplying by 4. So 8 × 4 = 32, and 7 × 4 = 28
multiplication, basic

Question 17

Find the missing number: 3, 5 : 8 :: 1, 3 : ?
Fibonacci pattern: each term is sum of previous two. 1 + 3 = 4
pattern, sequence

Question 18

Find the missing number: 6 : 36 :: 3 : ?
The relationship is square root. √3 = 9
square, roots

Question 19

Find the missing number: 21 : 15 :: 28 : ?
The relationship is subtracting 6. So 21 - 6 = 15, and 28 - 6 = 22
subtraction, basic

Question 20

Find the missing number: 5 : 28 :: 4 : ?
The relationship is square then add 3. 4² + 3 = 19
square, roots
