  1. What number continues: 1, 3, 7, 15, 31, ?

    Answer: 63

    Each term doubles and adds 1, so 31 x 2 + 1 = 63.

  2. If 5 workers build a wall in 10 days, how long for 10 workers at the same rate?

    Answer: 5 days

    Doubling the workers halves the time, so 10 / 2 = 5 days.

  3. What is the missing number: 81, 27, 9, 3, ?

    Answer: 1

    Each term is divided by 3, so 3 / 3 = 1.

  4. A class has 30 students and 60% are girls. How many girls are there?

    Answer: 18

    60% of 30 is 0.6 x 30 = 18.

  5. What number comes next: 11, 22, 33, 44, ?

    Answer: 55

    Each term increases by 11, so 44 + 11 = 55.

  6. If a number increased by 7 equals 20, what is the number?

    Answer: 13

    20 - 7 = 13.

  7. Complete the pattern: 1, 8, 27, 64, ?

    Answer: 125

    These are cube numbers, so the next is 5 x 5 x 5 = 125.
