  1. A number pattern starts 3, 7, 11, 15, ... What is the 10th term of the pattern?

    Answer: 39

    The pattern adds 4 each time, so the 10th term is 3 + 9 × 4 = 39.

  2. Which of the following fractions is closest in value to 0.4?

    Answer: 2/5

    2/5 equals exactly 0.4, so it is the closest.

  3. Mia buys 3 pens and 2 notebooks for $11. A pen costs $1.50. How much does one notebook cost?

    Answer: $3.25

    Three pens cost $4.50, leaving $6.50 for two notebooks, so each notebook is $3.25.

  4. If 4n − 7 = 25, what is the value of 2n + 1?

    Answer: 17

    Solving gives n = 8, so 2n + 1 = 17.

  5. What is the lowest common multiple (LCM) of 6, 8 and 12?

    Answer: 24

    24 is the smallest number that 6, 8 and 12 all divide into evenly.

  6. A rectangle's length is 3 cm more than its width. If its perimeter is 26 cm, what is its width?
