 KS2 Maths Quiz - Number Sequences (Year 5) (Questions)

In KS2 Maths as children advance to Year Five their knowledge of number sequences will increase. By now they should be able to recognise patterns that are increasing or decreasing by whatever amount in each step. They will also have a firm understanding of the properties of odd and even numbers and they will now be exposed to number sequences involving decimal numbers and fractions.

Number sequences involve finding a pattern in order to ascertain what the next number will be. Some patterns are straightforward, such as add 10, but others, like ones involving decimal numbers or fractions, can seem quite difficult to find. But once you know how, sequences with decimal numbers and fractions are just as easy to spot patterns in as ones made of whole numbers. It just takes a bit of practise.

1. Can you find the rule of this sequence? 6, 12, 18, 24, 30
 [x] The numbers increase in 6s [ ] The numbers increase in 3s [ ] The numbers increase in 5s [ ] The numbers increase in 4s
This sequence is the 6 times table
2. Can you find the rule of this sequence? 0, 0.1, 0.2, 0.3, 0.4
 [x] The numbers increase in 0.1s [ ] The numbers increase in 0.5s [ ] The numbers increase in 1s [ ] The numbers increase in 0.2s
The sequence would continue: 0.5, 0.6, 0.7, 0.8... etc
3. Can you find the rule of this sequence? 14, 21, 28, 35
 [ ] The numbers increase in 6s [x] The numbers increase in 7s [ ] The numbers increase in 5s [ ] The numbers increase in 9s
All of the numbers in this sequence are found in the 7 times table
4. What is the next number of the following sequence? 18, 27, 36, 45
 [ ] 50 [ ] 52 [x] 54 [ ] 56
The numbers are increasing by 9
5. What is the next number of the following sequence? 64, 56, 48, 40, 32
 [ ] 35 [ ] 28 [ ] 26 [x] 24
The numbers are decreasing by 8
6. What will be the tenth number of this sequence? 22, 33, 44, 55, 66
 [ ] 108 [ ] 110 [ ] 115 [x] 121
The numbers are increasing by 11
7. The sum of three even numbers will be what?
 [x] Even [ ] Odd [ ] It will end in 0 [ ] It will end in 5
The sum of 2 even numbers will be even. If you add 2 of the 3 numbers and then add another even it is the same as adding 2 even numbers
8. The sum of three odd numbers will be what?
 [ ] Even [x] Odd [ ] It will end in 0 [ ] It will end in 5
The sum of two odd numbers is even but add another odd number and the total will be odd
9. The difference between an odd number and an even number is what?
 [ ] Sometimes odd and sometimes even [x] Always odd [ ] Always even [ ] It always ends in 0
An odd + an odd = an even so an even - an odd = an odd
10. The difference between two odd numbers is what?
 [ ] Sometimes odd and sometimes even [ ] Always odd [x] Always even [ ] It always ends in 0
An odd + an even = an odd so an odd - an odd = an even
