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

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

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
