  1. What number comes next in the series: 2, 4, 8, 16, ___?

    Answer: 32

    Each term is doubled, so 16 × 2 = 32.

  2. Find the missing number: 3, 6, 9, ___, 15.

    Answer: 12

    This is an arithmetic sequence adding 3 each time, so 9 + 3 = 12.

  3. What comes next in the sequence: 1, 1, 2, 3, 5, 8, ___?

    Answer: 13

    Each term is the sum of the two preceding terms (Fibonacci sequence): 5 + 8 = 13.

  4. What is the next number: 100, 90, 81, 73, ___?

    Answer: 66

    The differences decrease by 1 each time (10, 9, 8, 7), so 73 − 7 = 66.

  5. Find the next term: 5, 10, 20, ___, 80.

    Answer: 40

    Each term is multiplied by 2, so 20 × 2 = 40.

  6. What is the next number in the series: 7, 14, 21, 28, ___?

    Answer: 35

    These are multiples of 7, so the next term is 7 × 5 = 35.

  7. Find the next term: 2, 5, 10, 17, 26, ___?

    Answer: 37

    The differences increase by 2 each step (3, 5, 7, 9, 11), so 26 + 11 = 37.
