Question 1

Find the missing number: 4 : sum of 2 terms = 10 :: 4 : sum of 2 terms = ?
Sum of 2 terms of AP: n/2 × (2a + (n-1)d). For 4, sum = 10
progression, sequence

Question 2

Find the missing number: 2 : 6 :: 3 : ?
The relationship is multiplying by 3. So 2 × 3 = 6, and 3 × 3 = 9
multiplication, basic

Question 3

Find the missing number: 30 : 6 :: 20 : ?
The relationship is dividing by 5. So 30 ÷ 5 = 6, and 20 ÷ 5 = 4
division, basic

Question 4

Find the missing number: 20 : 13 :: 21 : ?
The subtractor alternates: -7 then -6. So 21 - 6 = 15
subtraction, basic

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: 12 : 18 :: 5 : ?
The relationship follows an alternating addition pattern: +6, then +7. So 5 + 7 = 12
addition, basic

Question 7

Find the missing number: 18 : 6 :: 30 : ?
The relationship is dividing by 3. So 18 ÷ 3 = 6, and 30 ÷ 3 = 10
division, basic

Question 8

Find the missing number: 3 : 9 :: 10 : ?
The multiplier increases by 1: ×3 then ×4. So 10 × 4 = 40
multiplication, basic

Question 9

Find the missing number: 6 : 10 :: 14 : ?
The relationship is adding 4. So 6 + 4 = 10, and 14 + 4 = 18
addition, basic

Question 10

Find the missing number: 40 : 4 :: 55 : ?
The relationship is the digital root (repeated sum until single digit). Digital root of 40 = 4, of 55 = 1
digit, sum

Question 11

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

Question 12

Find the missing number: 10 : 40 :: 7 : ?
The multiplier increases by 1: ×4 then ×5. So 7 × 5 = 35
multiplication, basic

Question 13

Find the missing number: 7, 10 : 3 :: 2, ? : ?
In AP, common difference = 3. Next term after 2 is 5
progression, sequence

Question 14

Find the missing number: 24 : 6 :: 36 : ?
The relationship is dividing by 4. So 24 ÷ 4 = 6, and 36 ÷ 4 = 9
division, basic

Question 15

Find the missing number: 59 : 45 :: 84 : ?
The relationship is the product of digits. Product of digits of 59 = 45, product of digits of 84 = 32
product, digits

Question 16

Find the missing number: 43 : 4 :: 7 : ?
The relationship is the gap to the next prime. Gap after 7 is 4
prime, advanced

Question 17

Find the missing number: 26 : 19 :: 19 : ?
The relationship is subtracting 7. So 26 - 7 = 19, and 19 - 7 = 12
subtraction, basic

Question 18

Find the missing number: 6 : 36 :: 2 : ?
The relationship is square root. √2 = 4
square, roots

Question 19

Find the missing number: 2, 4 : 6 :: 3, 3 : ?
Fibonacci pattern: each term is sum of previous two. 3 + 3 = 6
pattern, sequence

Question 20

Find the missing number: 5 : 25 :: 9 : ?
