Question 1

Find the missing number: 7 : 49 :: 2 : ?
The relationship is square root. √2 = 4
square, roots

Question 2

Find the missing number: 9 : 16 :: 9 : ?
The relationship is adding 7 (or double for some patterns). Here 9 + 14 = 23
addition, basic

Question 3

Find the missing number: 25 : 22 :: 20 : ?
The subtractor alternates: -3 then -2. So 20 - 2 = 18
subtraction, basic

Question 4

Find the missing number: 234 : 24 :: 134 : ?
The relationship is the product of digits. Product of digits of 234 = 24, product of digits of 134 = 12
product, digits

Question 5

Find the missing number: 75 : 40 :: 82 : ?
The relationship is the difference between number and product of its digits. |82 - 16| = 66
product, digits

Question 6

Find the missing number: 1, 1, 2 : 4 :: 2, 1, 2 : ?
Tribonacci pattern: each term is sum of previous three. 2+1+2 = 5
pattern, sequence

Question 7

Find the missing number: 7, 12 : 5 :: 2, ? : ?
In AP, common difference = 5. Next term after 2 is 7
progression, sequence

Question 8

Find the missing number: 2, 1, 4 : 7 :: 2, 3, 2 : ?
Tribonacci pattern: each term is sum of previous three. 2+3+2 = 7
pattern, sequence

Question 9

Find the missing number: 2, 4 : 6 :: 1, 4 : ?
Fibonacci pattern: each term is sum of previous two. 1 + 4 = 5
pattern, sequence

Question 10

Find the missing number: 2 : sum of 3 terms = 15 :: 5 : sum of 3 terms = ?
Sum of 3 terms of AP: n/2 × (2a + (n-1)d). For 5, sum = 24
progression, sequence

Question 11

Find the missing number: 29 : 22 :: 29 : ?
The relationship is subtracting 7. So 29 - 7 = 22, and 29 - 7 = 22
subtraction, basic

Question 12

Find the missing number: 5 : 20 :: 4 : ?
The relationship is partial factorial (first 2 terms). For 4: 4 × 3 × ... = 12
factorial, advanced

Question 13

Find the missing number: 8 : 66 :: 7 : ?
The relationship is square then add 2. 7² + 2 = 51
square, roots

Question 14

Find the missing number: 35 : 18 :: 95 : ?
The relationship is the difference between number and its reverse. |95 - 59| = 36
reverse, digits

Question 15

Find the missing number: 94 : 49 :: 56 : ?
The relationship is reversing the digits. Reverse of 94 is 49, reverse of 56 is 65
reverse, digits

Question 16

Find the missing number: 16 : 12 :: 16 : ?
The relationship is subtracting 4. So 16 - 4 = 12, and 16 - 4 = 12
subtraction, basic

Question 17

Find the missing number: 9 : 17 :: 17 : ?
The relationship follows an alternating addition pattern: +8, then +9. So 17 + 9 = 26
addition, basic

Question 18

Find the missing number: 3 : 9 :: 3 : ?
The relationship is raising to the power of 2. So 3^2 = 9, and 3^2 = 9
square, power

Question 19

Find the missing number: 5 : 15 :: 2 : ?
The relationship is multiplying by 3. So 5 × 3 = 15, and 2 × 3 = 6
multiplication, basic

Question 20

Find the missing number: 11 : 2 :: 31 : ?
