  1. If the pattern is 2, 6, 18, 54, … what is the next number?

    Answer: 162

    Each term is multiplied by 3, so 54 × 3 = 162.

  2. A triangle has angles measuring 45°, 90°, and x°. What is x?

    Answer: 45°

    The angles of a triangle sum to 180°, so x = 180 – 45 – 90 = 45°.

  3. What is 15% of 200?

    Answer: 30

    15% of 200 = 0.15 × 200 = 30.

  4. Solve for n: 4n – 7 = 17

    Answer: n = 6

    4n = 17 + 7 = 24, so n = 24 ÷ 4 = 6.

  5. A cylinder has a radius of 3 cm and a height of 10 cm. What is its volume? (Use π ≈ 3.14)

    Answer: 282.6 cm³

    V = πr²h = 3.14 × 9 × 10 = 282.6 cm³.

  6. Which expression represents 'seven less than twice a number n'?

    Answer: 2n – 7

    'Twice a number n' is 2n, and 'seven less than' means subtract 7, giving 2n – 7.

  7. The table shows test scores: 78, 85, 92, 85, 70, 85, 90. What is the mode?
