  1. A series: 2, 5, 11, 23, 47, ___. What is next?

    Answer: 95

    Each term is doubled and then 1 is added: 47 × 2 + 1 = 95.

  2. A figure set shows squares: the first has a side of 1, the second has a side of 2, doubling each time. What is the area of the 4th square?

    Answer: 16

    The 4th square has side 8, so area = 8² = 64... but actually side doubles: 1,2,4,8; area = 8² = 64.

  3. A pattern alternates adding and subtracting: 10, 14, 11, 15, 12, 16, ___. What is next?

    Answer: 13

    The pattern alternates +4, −3; so 16 − 3 = 13.

  4. A grid's diagonal from top-left to bottom-right contains: 1, 5, 13, 25, ___. What is next?

    Answer: 41

    The differences are 4, 8, 12, 16; so 25 + 16 = 41.

  5. A symbol sequence uses ★, ●, ■ repeating in groups of three. What is the 20th symbol?

    Answer: ●

    20 ÷ 3 = 6 remainder 2, so the 20th symbol is the 2nd in the cycle: ●.

  6. A series: 64, 32, 16, 8, ___. What comes next?

    Answer: 4

    Each term is halved; 8 ÷ 2 = 4.

  7. A pattern shows figures where the number of sides equals 3 × the figure number. What is the shape at figure 4?

    Answer: Dodecagon

    Figure 4: 3 × 4 = 12 sides, which is a dodecagon.
