 # KS2 Maths Quiz - Number Sequences (Year 3) (Questions)

In KS2 Maths children will learn more about number sequences. This begins in Year Three with children recognising simple patterns, for example sequences increasing by 2, 3, 10 or 100 each time. They should also be able to recognise odd and even sequences of numbers.

Understanding number sequences is all about recognising patterns in the order of numbers. We can all see that in the order 1, 2, 3, 4, 5 the numbers are increasing by 1 each time. Therefore we have found the pattern. We know that the numbers are increasing by 1 so we know that the following number will be a 6. We just need to add 1 to 5.

How good are you at recognising patterns in number sequences? Can you find the rules for these number sequences in this quiz for 7-8 year olds?

1. Can you find the rule of this sequence? 5, 10, 15, 20, 25, 30
 [ ] The numbers increase in 2s [ ] The numbers increase in 3s [ ] The numbers increase in 5s [ ] The numbers increase in 10s
2. What are the next two numbers of the sequence? 3, 6, 9, 12
 [ ] 15, 18 [ ] 13, 14 [ ] 15, 17 [ ] 15, 20
3. Can you find the rule of this sequence? 3, 13, 23, 33
 [ ] The numbers increase in 2s [ ] The numbers increase in 3s [ ] The numbers increase in 5s [ ] The numbers increase in 10s

 [ ] 300 [ ] 350 [ ] 400 [ ] 420
5. How do we know a number is even?
 [ ] It ends in 0, 2, 4, 6 or 8 [ ] It ends in 1, 3, 5, 7 or 9 [ ] It ends in 5 [ ] It ends in 9
6. How do we know a number is odd?
 [ ] It ends in 6 [ ] It ends in 0, 2, 4, 6 or 8 [ ] It ends in 1, 3, 5, 7 or 9 [ ] It ends in 2 or 4
7. Which sequence is odd?
 [ ] 4, 6, 8, 10, 12 [ ] 30, 32, 34, 36, 38 [ ] 17, 21, 25, 29, 33 [ ] 12, 20, 28, 36, 44
8. Which is the next even number after 148?
 [ ] 158 [ ] 150 [ ] 160 [ ] 152
9. If you add two even numbers together the answer is always what?
 [ ] An odd number [ ] An even number [ ] A number ending in 2 [ ] A number ending in 0
10. If you add two odd numbers together the answer is always what?
 [ ] An odd number [ ] An even number [ ] A number ending in 5 [ ] A number ending in 2 KS2 Maths Quiz - Number Sequences (Year 3) (Answers)
1. Can you find the rule of this sequence? 5, 10, 15, 20, 25, 30
 [ ] The numbers increase in 2s [ ] The numbers increase in 3s [x] The numbers increase in 5s [ ] The numbers increase in 10s
This sequence is the 5 times table
2. What are the next two numbers of the sequence? 3, 6, 9, 12
 [x] 15, 18 [ ] 13, 14 [ ] 15, 17 [ ] 15, 20
The numbers are increasing in 3s
3. Can you find the rule of this sequence? 3, 13, 23, 33
 [ ] The numbers increase in 2s [ ] The numbers increase in 3s [ ] The numbers increase in 5s [x] The numbers increase in 10s
Each number (except the first) is 10 higher than the one before it
4. What is the next number of the sequence? 20, 120, 220, 320
 [ ] 300 [ ] 350 [ ] 400 [x] 420
The numbers are increasing by 100
5. How do we know a number is even?
 [x] It ends in 0, 2, 4, 6 or 8 [ ] It ends in 1, 3, 5, 7 or 9 [ ] It ends in 5 [ ] It ends in 9
All the even numbers can be divided by 2 and give a whole number
6. How do we know a number is odd?
 [ ] It ends in 6 [ ] It ends in 0, 2, 4, 6 or 8 [x] It ends in 1, 3, 5, 7 or 9 [ ] It ends in 2 or 4
If odd numbers are divided by 2 there will be a remainder or fraction left over
7. Which sequence is odd?
 [ ] 4, 6, 8, 10, 12 [ ] 30, 32, 34, 36, 38 [x] 17, 21, 25, 29, 33 [ ] 12, 20, 28, 36, 44
All the numbers end in 1, 3, 5, 7 or 9 so it must be odd
8. Which is the next even number after 148?
 [ ] 158 [x] 150 [ ] 160 [ ] 152
148 + 2 = 150
9. If you add two even numbers together the answer is always what?
 [ ] An odd number [x] An even number [ ] A number ending in 2 [ ] A number ending in 0
2 even numbers always make an even number but an even with an odd will make an odd number
10. If you add two odd numbers together the answer is always what?
 [ ] An odd number [x] An even number [ ] A number ending in 5 [ ] A number ending in 2
Even + even = even
Even + odd = odd
Odd + even = odd
Odd + odd = even
