### 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 go up or down in multiples from your times tables.

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

3, 6, 9, 12, ___

This is the 3 times table, and the missing number is 15.

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

Good luck, number detective!

We are counting on you...

2, 4, 6, 8, 10

Even numbers
EDDIE SAYS
Did you notice that these numbers end in 2, 4, 6, 8 and 0? We call these numbers even numbers. These numbers are also in our 2 times tables.

1, 3, 5, 7, 9, 11

Odd numbers
EDDIE SAYS
Did you notice that these were odd numbers? Numbers that end in 1, 3, 5, 7 and 9 are called odd numbers.
• Question 3

Look at the following number sequence.

Which number would come next?

4, 6, 8, 10, ?

12
EDDIE SAYS
Did you notice that this sequence was going up in even numbers? This is the same as going up in the 2 times table. The next even number after 10 is 12. Keep looking out for those even and odd numbers, detective!
• Question 4

Look at the following number sequence.

Which number would come next?

5, 7, 9, 11, 13, ?

15
EDDIE SAYS

• Question 5

Which number would come next in this sequence?

13, 15, 17, 19, ?

21
EDDIE SAYS

• Question 6

Which number would come next in this sequence?

14, 16, 18, 20, ?

22
EDDIE SAYS
This sequence is using numbers from our 2 times table, as all of the numbers are even. The next number in the 2 times tables is 22. How many 2s are in 22?

Which number comes next in the following sequence?

5, 10, 15, 20, ?

25
EDDIE SAYS
Did you notice that this sequence was going up in 5s? This sequence is using numbers from our 5 times table. The next number in our 5 times table is 25. How many 5s are in 25?

Which number comes next in this sequence?

70, 80, 90, 100, ?

110
EDDIE SAYS
What amount was this sequence increasing by each time? It's going up in 10s, and 10 more than 100 is 110. Remember to type your answer in figures, rather than words.
• Question 9

Which number comes next in the following sequence?

55, 60, 65, 70, ?
