### QUESTION 1 of 10

Number detective, you’ve arrived just in time!

We’re faced with a new puzzle and we hope you can help us solve it.

Can you work out which number comes next in this sequence?

6, 8, 10, 12, 14, __

Did you get 16?

This is an even number sequence and the next even number after 14 is 16.

Even numbers are numbers which end in 2, 4, 6, 8 or 0.

Which number is missing from this sequence?

3, 5, 7, __ , 11, 13

This is a sequence of odd numbers and the missing odd number, between 7 and 11, is 9.

Odd numbers are numbers which end in 1, 3, 5, 7 or 9.

Sometimes, sequences may go up or down in multiples from your times tables.

Which times table does this sequence form part of and can you figure out which number comes next?

3, 6, 9, 12, __

This is the three times table and the missing number is 15.

It’s now your turn to find the missing numbers.

Good luck number detective!

• Question 1

Use the grid below to select whether each number is odd or even.

EDDIE SAYS
How were your odd and even number detecting skills here? Remember that even numbers end in a 0, 2, 4, 6 or an 8 and odd numbers end in a 1, 3, 5, 7 or 9. If a number begins with an odd number but ends in an even number, it makes the whole number even.
• Question 2

Identify whether the numbers below are odd or even.

EDDIE SAYS
Did you identify the odd and even numbers here? The number 50 is trying to catch us out as it begins with an odd number BUT as it ends in a 0, it is an even number. It's time to put those detective skills to the test and work out the missing number in a sequence.
• Question 3

Look at the following number sequence.

Which number would come next?

Fill in the blank below.

EDDIE SAYS
Did you notice that this was a sequence of even numbers? The next even number after 84 is 86.
• Question 4

Look at the following number sequence.

Which number would come next?

Type it in the blank space below.

It's time for some odd numbers now detective. The next odd number after 89 is 91.
• Question 5

Which number would come next in this sequence?

68, 70, 72, 74, __

76
EDDIE SAYS
Did you notice what kind of sequence we had here? The missing number here is 76. This is an even number sequence and it is going up in 2s each time. 74 + 2 = 76.
• Question 6

Fill in the missing number in this sequence.

EDDIE SAYS
How much was this sequence going up in each time? This is going up in 10s and 10 more than 230 is 240.
• Question 7

Which number comes next in the following sequence?

Fill in the blank below.

EDDIE SAYS
Here we have a sequence going up in 5s. The next multiple of 5 after 110 is 115. Remember that multiples of 5 always end in a 5 or a 0.
