CCAT Spatial Reasoning: Series 5

Question 1

A series of figures shows a star with an increasing number of points: 4, 5, 6, 7... What comes next?

Accepted Answer

8

Answer

Each figure adds one point to the star, so the next star has 8 points.

Question 2

In a visual matrix series, a small black square moves one cell to the right each step in a 4-cell row. After reaching the rightmost cell, it wraps to the leftmost cell. If it starts in cell 1, which cell is it in after 9 moves?

Accepted Answer

Cell 2

Answer

After 9 moves from cell 1: (1 + 9 − 1) mod 4 + 1 = 9 mod 4 + 1 = 1 + 1 = 2, so it's in cell 2.

Question 3

A series shows concentric rings added to a circle: figure 1 has 1 ring, figure 2 has 2 rings, figure 3 has 3 rings. Each new ring is the same thickness. Which figure first has more than 5 rings?

Accepted Answer

Figure 6

Answer

Since each figure adds exactly one ring, Figure 6 is the first to have 6 rings, which exceeds 5.

Question 4

In a series, each shape is reflected horizontally from the previous one. If Figure 1 shows an arrow pointing right, what does Figure 4 show?

Accepted Answer

Arrow pointing right

Answer

Reflecting horizontally alternates left/right: F1=right, F2=left, F3=right, F4=left — but even figures point left, so F4 points left.

Question 5

A series of figures shows the number of sides of each polygon increasing by 1: triangle (3), square (4), pentagon (5)... What is the 7th shape in the series?

Accepted Answer

Nonagon (9 sides)

Answer

The first shape (triangle) has 3 sides, so the nth shape has n+2 sides; the 7th shape has 7+2 = 9 sides (nonagon).
