 # Identify Sequence Types and Find Missing Numbers

In this worksheet, students will identify missing numbers in sequences of odd and even numbers, as well as times table sequences. Key stage:  KS 2

Curriculum topic:   Verbal Reasoning

Curriculum subtopic:   Number Sequences

Difficulty level:   ### 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...

4 times table
EDDIE SAYS
Hey there number detective! All of these numbers are in the 4 times tables. If we keep counting up in 4s from 0, we will say all of these numbers.
• Question 2

Which times table are the following numbers in?

21                  9                     12                  15                   36

3 times table
EDDIE SAYS
Did you recognise these numbers from the 3 times table? If you practise counting up in 3s, it will improve your number detective skills.
• Question 3

Which times table do all of the numbers below appear in?

16             80              24               8              72

8 times table
EDDIE SAYS
If we start from 0 and count up in 8s, we would say all of these numbers. Did you know that any number in the 8 times table is also in the 2 and 4 times table?
• Question 4

Which number is missing from the following times table sequence?

16, 24, __ , 40, 48

32
EDDIE SAYS
Did your detective eyes identify this as an 8 times table sequence? The next number in the 8 times table after 24 is 32.
• Question 5

Which number is missing from this sequence.

Fill in the blank below.

EDDIE SAYS
How much was the sequence going up by each time here? This sequence is going up in the 4 times table and the next number in the 4 times table after 20 is 24.
• Question 6

Which number is missing from this sequence?

Fill in the blank below.

EDDIE SAYS
It's back to the 8 times table for us number detective! 6 x 8 = 48 and the next number in the sequence needs to be the answer to 7 x 8. A great way to remember this is with the rhyme: 5, 6, 7, 8... 56 is 7 x 8!
• Question 7

Which number is missing from the following sequence?

21, 24, __ , 30, 33

27
EDDIE SAYS
Did you notice that this sequence uses numbers in the 3 times table? The next number after 24 in the 3 times table is 27.
• Question 8

Which number is missing from this sequence?

64, 72, 80, __ , 96

88
EDDIE SAYS
It's more of my favourite 8 times table for us here! The next number in the sequence needs to be 8 more than 80. This makes the correct answer 88.
• Question 9

Match each sequence to its times table.

## Column B

6, 9, 12, 15
3 times table
15, 20, 25, 30
5 times table
32, 40, 48, 56
8 times table
20, 24, 28, 32
4 times table
90, 100, 110, 120
10 times table
EDDIE SAYS
How many matches did you spot? Count carefully between the numbers in the sequences to see how much they are increasing by.
• Question 10

Match each sequence to its missing number.

## Column B

15, 18, __ , 24, 27
21
20, 24, __ , 32, 40
28
72, 80, __ , 96
88
EDDIE SAYS
I'm counting on you to count carefully from each number to the next in questions like this! The first sequence is going up in the 3 times table and 3 more than 18 is 21. The next sequence is going up in 4s and 4 more than 24 is 28. The final sequence is going up in 8s and 8 more than 80 is 88. Excellent number detective skills!
