  1. A series reads: 7, 14, 28, 56, ___. What comes next?

    Answer: 112

    Each term doubles the previous one, so 56 × 2 = 112.

  2. Figures rotate 45° clockwise each step. After four steps from 0°, the arrow points at ___.

    Answer: 180°

    Four steps of 45° each equals 180°, so the arrow points straight down.

  3. A number pattern: 3, 3, 6, 18, 72, ___. What is next?

    Answer: 360

    Each term is multiplied by 1, 2, 3, 4, 5 in sequence; 72 × 5 = 360.

  4. In a pattern, shaded squares move one column to the right each step. At step 4, the shaded square is in column 5. At step 7, which column is it in?

    Answer: 8

    The shaded square advances one column per step, so from step 4 to step 7 is 3 more steps: column 5 + 3 = 8.

  5. A letter series: Z, X, V, T, ___. What comes next?

    Answer: R

    Each letter decreases by 2 positions in the alphabet, so T − 2 = R.

  6. A grid has three rows where each cell equals the product of its row and column number. What is the value in row 4, column 3?

    Answer: 12

    Row 4 × column 3 = 4 × 3 = 12.

  7. A series of shapes alternates between increasing sides: triangle, square, pentagon, hexagon, ___.

    Answer: Heptagon

    Each shape gains one additional side, so after hexagon (6) comes heptagon (7).
