Question 1

Find the missing number: 2 : 5 (n=2) :: 8 : ?
The nth term formula: a + (n-1)d. For 8, term 2 = 11

Question 2

Find the missing number: 4 : 13 :: 14 : ?
The relationship is adding 9. So 4 + 9 = 13, and 14 + 9 = 23

Question 3

Find the missing number: 5 : 7 :: 17 : ?
The relationship is the next prime number. Next prime after 17 is 19

Question 4

Find the missing number: 4 : 8 :: 8 : ?
The relationship is multiplying by 2. So 4 × 2 = 8, and 8 × 2 = 16

Question 5

Find the missing number: 27 : 9 :: 7 : ?
The inverse relationship: multiply by 3. So 7 × 3 = 21

Question 6

Find the missing number: 21 : 16 :: 35 : ?
The subtractor increases: -5 then -7. So 35 - 7 = 28

Question 7

Find the missing number: 8 : 40 :: 4 : ?
The relationship is multiplying by 5. So 8 × 5 = 40, and 4 × 5 = 20

Question 8

Find the missing number: 7 : 11 :: 11 : ?
The relationship follows an alternating addition pattern: +4, then +5. So 11 + 5 = 16

Question 9

Find the missing number: 3 : 6 :: 3 : ?
The relationship is factorial. 3! = 6, 3! = 6

Question 10

Find the missing number: 8 : 81 :: 6 : ?
The relationship is the next consecutive square. (6+1)² = 49

Question 11

Find the missing number: 8 : 18 (n=3) :: 6 : ?
The nth term formula: a + (n-1)d. For 6, term 3 = 16

Question 12

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

Question 13

Find the missing number: 24 : 20 :: 35 : ?
The subtractor alternates: -4 then -3. So 35 - 3 = 32

Question 14

Find the missing number: 24 : 21 :: 24 : ?
The relationship is subtracting 3. So 24 - 3 = 21, and 24 - 3 = 21

Question 15

Find the missing number: 58 : 143 :: 53 : ?
The relationship is the sum of number and its reverse. 53 + 35 = 88

Question 16

Find the missing number: 25 : 16 :: 23 : ?
The relationship is subtracting 9. So 25 - 9 = 16, and 23 - 9 = 14

Question 17

Find the missing number: 4 : 12 :: 2 : ?
The multiplier increases by 1: ×3 then ×4. So 2 × 4 = 8

Question 18

Find the missing number: 3, 5 : 8 :: 1, 2 : ?
Fibonacci pattern: each term is sum of previous two. 1 + 2 = 3

Question 19

Find the missing number: 7 : 19 (n=4) :: 6 : ?
The nth term formula: a + (n-1)d. For 6, term 4 = 18

Question 20

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