### 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!

We are counting on you...

• Question 1

Which times table is the following sequence using?

56, 64, 72, 80, 88

8 times table
EDDIE SAYS
Hi number detective! Did you recognise these numbers from the 8 times table? The sequence is adding 8 each time. What number would come next in the sequence?
• Question 2

Which times table is the following sequence using?

27, 36, 45, 54, 63

9 times table
EDDIE SAYS
Did you spot the nine times table here? Let me teach you a sneaky detective trick here. If you add the digits up in any multiple of 9, the answer should equal 9! 27 --> 2 + 7 = 9 45 --> 4 + 5 = 9 That's how I knew all of these numbers were in the 9 times table really quickly - try this one next time detective.
• Question 3

Which times table is the following sequence using?

24, 30, 36, 42, 48

6 times table
EDDIE SAYS
All of these numbers are in the 6 times table. Every answer in the 6 times table is even. I knew it couldn't be the 5 times table, as numbers in the 5 times table only end in a 5 or a 0.
• Question 4

Which number is missing from the following sequence?

36, 42, 48, __ , 60, 66

54
EDDIE SAYS
Did you spot which times table the sequence was using? The sequence adds 6 each time and all of these numbers are in the 6 times table. The next number in the 6 times table after 48 is 54. Can you work out how many 6s are in 54?
• Question 5

Which number is missing from the following sequence?

Fill in the blank below.

EDDIE SAYS
Here we have a sequence going up in the 11 times table. 11 more than 55 is 66. This makes 66 the correct answer.
• Question 6

Which number is missing from the following sequence?

Fill in the blank below.

EDDIE SAYS
It's 9 times table time! The next number in the 9 times table after 54 is 63. Remember that all of the digits in the 9 times table add up to 9.
• Question 7

Which number is missing from the following sequence?

42, 48, 54, __ , 66

60
EDDIE SAYS
Did you spot our 6 times table here? The next number in the 6 times table after 54 is 60. Keep up the great work!
• Question 8

Which number is missing from the following sequence?

88, 99, 110, __ , 132

121
EDDIE SAYS
Here are some numbers higher up in our 11 times table. 11 more than 110 is 121. The 11 times table does get a bit harder to spot after 99 as the pattern changes, so be sure to take your time here.
• Question 9

Match the sequences to the times tables that they are using.

## Column B

27, 36, 45, 54
9 times table
88, 99, 110, 121
11 times table
12, 18, 24, 30
6 times table
EDDIE SAYS
Did you find all the matches number detective? If you count carefully from one number to the next, you can work out how much the sequence is going up in.
• Question 10

Match the sequences below to the times table they are using.

## Column B

45, 54, 63, 72
9 times table
24, 32, 40, 48
8 times table
9, 12, 15, 21
3 times table

Careful counting helps us in this question detective. If we don't know the times tables off by heart, we can count carefully from one number to the next. Excellent number work detective!
