Logical Reasoning Test Practice Course: Inductive patterns in words and tables

1. Question 1 sur 16

   A row of lights repeats the pattern red, blue, blue, green. What colour is the 37th light?

   • ARed
   • BGreen
   • CBlue
   Voir la réponse

   Réponse: A. Red

   The pattern repeats every 4 lights. 37 ÷ 4 = 9 remainder 1, so the 37th light is the 1st colour in the pattern: red.

2. Question 2 sur 16

   A rule turns 2 into 7, 5 into 16, and 10 into 31. What does the same rule turn 7 into?

   • A21
   • B14
   • C25
   • D22
   Voir la réponse

   Réponse: D. 22

   The rule is "multiply by 3, then add 1": 2 × 3 + 1 = 7, 5 × 3 + 1 = 16. So 7 × 3 + 1 = 22.

3. Question 3 sur 16

   In the table, each row follows the same rule. What number replaces the question mark?

   First	Second	Third
   4	6	10
   7	8	15
   9	5	?

   • A13
   • B4
   • C14
   • D45
   Voir la réponse

   Réponse: C. 14

   In each row, the third number is the sum of the first two: 4 + 6 = 10, 7 + 8 = 15. So 9 + 5 = 14.

4. Question 4 sur 16

   In the table, column C is worked out from columns A and B in the same way in every row. What number replaces the question mark?

   A	B	C
   3	4	12
   5	6	30
   2	9	?

   • A7
   • B27
   • C18
   • D11
   Voir la réponse

   Réponse: C. 18

   In each row, the third number is the first times the second: 3 × 4 = 12, 5 × 6 = 30. So 2 × 9 = 18.

5. Question 5 sur 16

   Each row of the table follows the same rule. What number replaces the question mark?

   Numéro	Next	Last
   2	4	8
   3	9	27
   5	?	125

   • A10
   • B15
   • C50
   • D25
   Voir la réponse

   Réponse: D. 25

   Each row shows a number, its square and its cube: 2, 4, 8 and 3, 9, 27. For 5: 5 × 5 = 25 and 25 × 5 = 125.

6. Question 6 sur 16

   A 3 × 3 grid is described row by row. Row 1: 1 circle, 2 circles, 3 circles. Row 2: 2 squares, 3 squares, 4 squares. Row 3: 3 triangles, 4 triangles, ?. What belongs in the missing cell?

   • A6 triangles
   • B4 circles
   • C5 triangles
   • D5 squares
   Voir la réponse

   Réponse: C. 5 triangles

   Each row keeps one shape and adds one more shape per cell. Each row also starts one higher than the row above. Row 3 runs 3, 4, 5 triangles.

7. Question 7 sur 16

   In this grid, each row and each column contains the letters A, B and C once. Which letter replaces the question mark?

   Column 1	Column 2	Column 3
   A	B	C
   C	A	B
   B	?	A

   • AC
   • BA
   • CB
   Voir la réponse

   Réponse: A. C

   Row 3 already has B and A, so it needs C. The middle column (B, A, ?) also needs C.

8. Question 8 sur 16

   A system makes codes like this: CAT becomes CAT3, HOUSE becomes HOUSE5, and DOOR becomes DOOR4. What code does TABLE get?

   • A5TABLE
   • BTABLE5
   • CTABLE6
   • DTABLE4
   Voir la réponse

   Réponse: B. TABLE5

   The number at the end is the number of letters in the word. TABLE has 5 letters, so TABLE5.

9. Question 9 sur 16

   Employee IDs follow a pattern. Lee Chan, hired in 2019 in department 4, has ID CH19-4. Ana Ruiz, hired in 2021 in department 2, has ID RU21-2. What is the ID for Omar Patel, hired in 2023 in department 7?

   • AOM23-7
   • BPA7-23
   • CPA23-7
   • DPA2023-7
   Voir la réponse

   Réponse: C. PA23-7

   The ID is the first two letters of the last name, the last two digits of the hiring year, a dash, and the department number.

10. Question 10 sur 16

    Three of these letter groups follow the same rule. Which group does not?

    • AGIK
    • BACE
    • CLMN
    • DBDF
    Voir la réponse

    Réponse: C. LMN

    In ACE, BDF and GIK, each letter skips one letter of the alphabet. LMN uses letters right next to each other.

11. Question 11 sur 16

    A machine is serviced every 5 days. The first service is on a Monday. On what day of the week is the 4th service?

    • AThursday
    • BFriday
    • CSunday
    • DTuesday
    Voir la réponse

    Réponse: D. Tuesday

    The 4th service is 3 gaps after the first: 3 × 5 = 15 days. 15 days is 2 weeks and 1 day, so Monday + 1 day = Tuesday.

12. Question 12 sur 16

    In this grid, every row and every column adds up to the same total. What number replaces the question mark?

    Column 1	Column 2	Column 3
    8	1	6
    3	5	7
    4	9	?

    • A1
    • B6
    • C2
    • D3
    Voir la réponse

    Réponse: C. 2

    Each full row adds to 15 (8 + 1 + 6). Row 3: 4 + 9 + ? = 15, so ? = 2. The last column checks: 6 + 7 + 2 = 15.

13. Question 13 sur 16

    A rule turns 3 into 10, 6 into 37, and 8 into 65. What does the same rule turn 5 into?

    • A26
    • B11
    • C16
    • D25
    Voir la réponse

    Réponse: A. 26

    The rule is "square the number, then add 1": 3 × 3 + 1 = 10, 6 × 6 + 1 = 37. So 5 × 5 + 1 = 26.

14. Question 14 sur 16

    In the table, each result is worked out from the first two numbers with the same two steps. What number replaces the question mark?

    First	Second	Résultat
    9	4	10
    12	5	14
    15	8	?

    • A7
    • B23
    • C14
    • D46
    Voir la réponse

    Réponse: C. 14

    Subtract the second number from the first, then double it: (9 − 4) × 2 = 10, (12 − 5) × 2 = 14. So (15 − 8) × 2 = 14.

15. Question 15 sur 16

    A rule changes STOP into POTS and LIVE into EVIL. What does the same rule change DRAW into?

    • ARAWD
    • BARDW
    • CWARD
    • DWRAD
    Voir la réponse

    Réponse: C. WARD

    The rule writes each word backwards. DRAW backwards is WARD.

16. Question 16 sur 16

    The table shows boxes packed per day. Each worker's numbers follow their own pattern. How many boxes will Ann pack on Friday?

    Worker	Mon	Tue	Wed	Thu	Fri
    Ann	2	4	8	16	?
    Bo	5	9	13	17	21

    • A24
    • B18
    • C32
    • D20
    Voir la réponse

    Réponse: C. 32

    Ann's numbers double each day: 2, 4, 8, 16, so Friday is 32. Bo's pattern (add 4) is a different rule and does not apply to Ann.
