  1. What is the next number in the sequence: 3, 7, 15, 31, 63, ___?

    Answer: 127

    Each term is double the previous term plus 1: 63×2+1=127.

  2. If all firefighters are first responders, and some first responders are paramedics, which statement must be true?

    Answer: Some firefighters may be paramedics

    Since only some first responders are paramedics, firefighters (a subset) could overlap with paramedics but it is not guaranteed.

  3. What is the next letter in the sequence: A, C, F, J, O, ___?

    Answer: U

    The gaps increase by one each time (+2, +3, +4, +5, +6), so O (position 15) + 6 = U (position 21).

  4. A fire truck parked facing North turns 90° clockwise, then 180° counterclockwise. What direction is it now facing?

    Answer: West

    North + 90° clockwise = East; East + 180° counterclockwise = West.

  5. A fire hose fills a 500-gallon tank in 10 minutes. How many tanks can it fill in 45 minutes?

    Answer: 4.5

    45 minutes ÷ 10 minutes per tank = 4.5 tanks.

  6. A dispatch map shows Station A at coordinates (2, 3) and a fire at (8, 7). What is the approximate straight-line distance?

    Answer: 7.2 units

    Distance = √((8−2)² + (7−3)²) = √(36+16) = √52 ≈ 7.2 units.

  7. A pattern follows: 2, 4, 8, 16, ___. What number comes next?

    Answer: 32

    Each term is double the previous: 16×2 = 32.
