Question 1

Find the missing number: 31 : 6 :: 2 : ?
The relationship is the gap to the next prime. Gap after 2 is 1
prime, advanced

Question 2

Find the missing number: 2 : sum of 2 terms = 8 :: 5 : sum of 2 terms = ?
Sum of 2 terms of AP: n/2 × (2a + (n-1)d). For 5, sum = 14
progression, sequence

Question 3

Find the missing number: 134 : 12 :: 134 : ?
The relationship is the product of digits. Product of digits of 134 = 12, product of digits of 134 = 12
product, digits

Question 4

Find the missing number: 19 : 27 :: 8 : ?
The relationship follows an alternating addition pattern: +8, then +9. So 8 + 9 = 17
addition, basic

Question 5

Find the missing number: 8 : 24 :: 2 : ?
The multiplier increases by 1: ×3 then ×4. So 2 × 4 = 8
multiplication, basic

Question 6

Find the missing number: 7 : 11 (n=3) :: 3 : ?
The nth term formula: a + (n-1)d. For 3, term 3 = 7
progression, sequence

Question 7

Find the missing number: 31 : 28 :: 29 : ?
The subtractor alternates: -3 then -2. So 29 - 2 = 27
subtraction, basic

Question 8

Find the missing number: 12 : 19 :: 7 : ?
The relationship follows an alternating addition pattern: +7, then +8. So 7 + 8 = 15
addition, basic

Question 9

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

Question 10

Find the missing number: 6 : 16 :: 2 : ?
The relationship is adding 10. So 6 + 10 = 16, and 2 + 10 = 12
addition, basic

Question 11

Find the missing number: 4 : 64 :: 5 : ?
The relationship is cubing the number. So 4³ = 64, and 5³ = 125
square, power

Question 12

Find the missing number: 47 : 11 :: 31 : ?
The relationship is the sum of digits. Sum of digits of 47 = 11, sum of digits of 31 = 4
digit, sum

Question 13

Find the missing number: 7 : 11 :: 23 : ?
The relationship is the next prime number. Next prime after 23 is 29
prime, advanced

Question 14

Find the missing number: 74 : 2 :: 22 : ?
The relationship is the digital root (repeated sum until single digit). Digital root of 74 = 2, of 22 = 4
digit, sum

Question 15

Find the missing number: 9 : 16 :: 3 : ?
The relationship is adding 7 (or double for some patterns). Here 3 + 14 = 17
addition, basic

Question 16

Find the missing number: 7 : 11 :: 10 : ?
The relationship is adding 4 (or double for some patterns). Here 10 + 8 = 18
addition, basic

Question 17

Find the missing number: 69 : 15 :: 54 : ?
The relationship is the difference between number and product of its digits. |54 - 20| = 34
product, digits

Question 18

Find the missing number: 20 : 17 :: 34 : ?
The subtractor alternates: -3 then -2. So 34 - 2 = 32
subtraction, basic

Question 19

Find the missing number: 3 : 7 :: 3 : ?
The relationship is adding 4 (or double for some patterns). Here 3 + 8 = 11
addition, basic

Question 20

Find the missing number: 67 : 4 :: 50 : ?
The relationship is the digital root (repeated sum until single digit). Digital root of 67 = 4, of 50 = 5
digit, sum
