Question 1

Find the missing number: 4 : 48 :: 3 : ?
The relationship is double factorial. 2 × 4! = 48, 2 × 3! = 12
factorial, advanced

Question 2

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

Question 3

Find the missing number: 245 : 40 :: 235 : ?
The relationship is the product of digits. Product of digits of 245 = 40, product of digits of 235 = 30
product, digits

Question 4

Find the missing number: 35 : 26 :: 21 : ?
The subtractor increases: -9 then -10. So 21 - 10 = 11
subtraction, basic

Question 5

Find the missing number: 10 : 40 :: 6 : ?
The relationship is multiplying by 4. So 10 × 4 = 40, and 6 × 4 = 24
multiplication, basic

Question 6

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

The relationship is the next consecutive square. (5+1)² = 36
square, roots

Question 8

Find the missing number: 95 : 14 :: 53 : ?
The relationship is the sum of digits. Sum of digits of 95 = 14, sum of digits of 53 = 8
digit, sum

Question 9

Find the missing number: 66 : 132 :: 49 : ?
The relationship is the sum of number and its reverse. 49 + 94 = 143
reverse, digits

Question 10

Find the missing number: 45 : 20 :: 27 : ?
The relationship is the product of digits. Product of digits of 45 = 20, product of digits of 27 = 14
product, digits

Question 11

Find the missing number: 3 : 9 :: 3 : ?
The relationship is squaring the number. So 3² = 9, and 3² = 9
square, power

Question 12

Find the missing number: 65 : 56 :: 91 : ?
The relationship is reversing the digits. Reverse of 65 is 56, reverse of 91 is 19
reverse, digits

Question 13

Find the missing number: 2, 3, 2 : 7 :: 2, 2, 2 : ?
Tribonacci pattern: each term is sum of previous three. 2+2+2 = 6
pattern, sequence

Question 14

Find the missing number: 45 : 9 :: 69 : ?
The relationship is the difference between number and its reverse. |69 - 96| = 27
reverse, digits

Question 15

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