Level 3
The figures shows sequence of patterns of an arrangement of dots. '1st column' indicates the number of dots in the first column and the 'Total' indicates the number of dots in each pattern.
Find the number of dots in Figure 9.
Find the number of dots in Figure 20.
If the first column of a figure is made up of 21 dots, find the number of dots that make up the figure.

Level 3 PSLE
Victoria hung some identical oval rings vertically. The thickness of each oval ring was 1 cm. The figure shows how the oval rings are connected.
What was the distance from the top of the 1st oval ring to the bottom of the 3rd oval ring?
The distance from the top of the 1st ring to the bottom of the last ring was 177 cm. How many oval rings did Victoria hang altogether?
