Question 1

Find the missing number: 19 : 4 :: 11 : ?
The relationship is the gap to the next prime. Gap after 11 is 2
prime, advanced

Question 2

Find the missing number: 20 : 2 :: 25 : ?
The relationship is the digital root (repeated sum until single digit). Digital root of 20 = 2, of 25 = 7
digit, sum

Question 3

Find the missing number: 31 : 37 :: 13 : ?
The relationship is the next prime number. Next prime after 13 is 17
prime, advanced

Question 4

Find the missing number: 5 : 28 :: 2 : ?
The relationship is square then add 3. 2² + 3 = 7
square, roots

Question 5

Find the missing number: 2 : 1 :: 13 : ?
The relationship is the gap to the next prime. Gap after 13 is 4
prime, advanced

Question 6

Find the missing number: 99 : 1 :: 13 : ?
The relationship is sum of digits plus 1 (wrapping at 9). For 13: 4 + 1 = 5
digit, sum

Question 7

Find the missing number: 37 : 29 :: 26 : ?
The subtractor increases: -8 then -9. So 26 - 9 = 17
subtraction, basic

Question 8

Find the missing number: 8 : 12 :: 16 : ?
The relationship follows an alternating addition pattern: +4, then +5. So 16 + 5 = 21
addition, basic

Question 9

Find the missing number: 6 : 36 :: 7 : ?
The relationship is squaring the number. So 6² = 36, and 7² = 49
square, power

Question 10

Find the missing number: 6 : 49 :: 4 : ?
The relationship is the next consecutive square. (4+1)² = 25
square, roots

Question 11

Find the missing number: 13 : 16 :: 18 : ?
The relationship follows an alternating addition pattern: +3, then +4. So 18 + 4 = 22
addition, basic

Question 12

Find the missing number: 20 : 17 :: 28 : ?
The subtractor alternates: -3 then -2. So 28 - 2 = 26
subtraction, basic

Question 13

Find the missing number: 48 : 84 :: 81 : ?
The relationship is reversing the digits. Reverse of 48 is 84, reverse of 81 is 18
reverse, digits

Question 14

Find the missing number: 97 : 7 :: 57 : ?
The relationship is the digital root (repeated sum until single digit). Digital root of 97 = 7, of 57 = 3
digit, sum

Question 15

Find the missing number: 8 : 14 :: 4 : ?
The relationship is adding 6 (or double for some patterns). Here 4 + 12 = 16
addition, basic

Question 16

Find the missing number: 48 : 12 :: 24 : ?
The relationship is dividing by 4. So 48 ÷ 4 = 12, and 24 ÷ 4 = 6
division, basic

Question 17

Find the missing number: 69 : 15 :: 81 : ?
The relationship is the sum of digits. Sum of digits of 69 = 15, sum of digits of 81 = 9
digit, sum

Question 18

Find the missing number: 2 : 8 :: 2 : ?
The relationship is raising to the power of 3. So 2^3 = 8, and 2^3 = 8
square, power

Question 19

Find the missing number: 62 : 50 :: 25 : ?
The relationship is the difference between number and product of its digits. |25 - 10| = 15
product, digits

Question 20

Find the missing number: 10 : 18 :: 3 : ?
The relationship is adding 8. So 10 + 8 = 18, and 3 + 8 = 11
addition, basic
