Police Math Test Police Math Algebra and Number Sequences 2 — Questions and Answers
Question 1: Solve: 5x = 45
- x = 7
- x = 8
- x = 9 (Correct answer)
- x = 10
Correct answer: x = 9
Divide both sides by 5 to get x = 45 ÷ 5 = 9.
Question 2: What is the next number in the sequence: 3, 6, 12, 24, ___?
- 36
- 42
- 48 (Correct answer)
- 56
Correct answer: 48
Each term is multiplied by 2, so 24 × 2 = 48.
Question 3: If x/4 = 7, what is x?
- 24
- 26
- 28 (Correct answer)
- 30
Correct answer: 28
Multiply both sides by 4 to get x = 7 × 4 = 28.
Question 4: A sergeant has y officers on duty. After 3 more officers join the shift, there are 15 on duty. What was y?
- 10
- 11
- 12 (Correct answer)
- 13
Correct answer: 12
The equation is y + 3 = 15, so y = 15 − 3 = 12.
Question 5: What is the missing number in the sequence: 100, 91, 82, 73, ___?
- 60
- 62
- 64 (Correct answer)
- 66
Correct answer: 64
Each term decreases by 9, so 73 − 9 = 64.
Question 6: Solve for x: 6x − 4 = 2x + 16
- x = 3
- x = 4
- x = 5 (Correct answer)
- x = 6
Correct answer: x = 5
Subtract 2x from both sides: 4x − 4 = 16; add 4: 4x = 20; divide by 4: x = 5.
Question 7: If n + n + n = 39, what is n?
- 11
- 12
- 13 (Correct answer)
- 14
Correct answer: 13
The equation simplifies to 3n = 39, so n = 39 ÷ 3 = 13.
