Number and Pattern Shapes

How would you describe this pattern's rule?
99, 97, 95, 93, 91

• Subtract 1

• Add 2

• Subtract 2

• Add 3

What would be the 99th number in the pattern shown below?

10, 20, 30, 40, 50

• 99

• 900

• 909

• 990

Here is a sequence of patterns made from squares and circles. The sequence continues in the same way. Calculate how many squares there will be in the pattern which has 25 circles.

• 12 circles

• 9 circles

• 15 circles

• 20 circles

Here is a repeating pattern of shapes.
Each shape is numbered.
The pattern continues in the same way.
Write the numbers of the next two stars in the pattern.

• 11 and 16

• 24 and 30

• 12 and 16

• 12 and 30

Here is part of a number square.

The shaded numbers are part of a sequence.

Explain the rule for the sequence.

• Subtracting 9 each time

• Adding 12 each time

• Adding 9 each time

• Subtracting 20 each time

In this sequence each number is double the previous number.

Write in the missing numbers.

• 0.75, 1.2, 69

• 0.45, 1.5, 69

• 1.2, 1.75, 96

• 0.75, 1.5, 96

Write the missing numbers in this sequence.

• 6 and 2

• 8 and 2

• 8 and 12

• 6 and 12

Write the two missing numbers in this sequence.

• 100 and 65

• 96 and 65

• 101 and 67

• 100 and 56

The first two numbers in this sequence are 2.1 and 2.2

The sequence then follows the rule :

‘to get the next number, add the two previous numbers’

Write in the next two numbers in the sequence.

• 10.8 and 17.1

• 11.6 and 18.2

• 10.8 and 17.3

• 10.6 and 18.2

The numbers in this sequence increase by the same amount each time.

Write the missing numbers.

• 34, 56, 74

• 35, 56 and 70

• 36, 65, 72

• 35, 65, 72
