Question

These numbers form a pattern.

17 , 21 , 25 , 29 , ? , ?


The next 2 numbers in the pattern are:

Worked Solution

The next term is found by adding 4 to the previous term
Starting number = 17
2nd number = 17 + 4 = 21
3rd number = 21 + 4 = 25
4th number = 25 + 4 = 29
5th number = 29 + 4 = 33
6th number = 33 + 4 = 37


Therefore, the next 2 numbers are 33 and 37.

Question

These numbers form a pattern.

23 , 20 , 17 , 14 , ? , ?


The next 2 numbers in the pattern are:

Worked Solution

The next term is found by subtracting 3 from the previous term
Starting number = 23
2nd number = 23 −- 3 = 20
3rd number = 20 −- 3 = 17
4th number = 17 −- 3 = 14
5th number = 14 −- 3 = 11
6th number = 11 −- 3 = 8


Therefore, the next 2 numbers are 11 and 8.

Question

These numbers form a pattern.

9 , 15 , 21 , 27 , ? , ?


The next 2 numbers in the pattern are:

Worked Solution

The next term is found by adding 6 to the previous term
Starting number = 9
2nd number = 9 + 6 = 15
3rd number = 15 + 6 = 21
4th number = 21 + 6 = 27
5th number = 27 + 6 = 33
6th number = 33 + 6 = 39


Therefore, the next 2 numbers are 33 and 39.

Question

These numbers form a pattern.

800 , 400 , 200 , 100 , ? , ?


The next 2 numbers in the pattern are:

Worked Solution

The next number in the pattern is found by halving the previous number.
Starting number = 800
2nd number = 800 ÷\div 2 = 400
3rd number = 400 ÷\div 2 = 200
4th number = 200 ÷\div 2 = 100
5th number = 100 ÷\div 2 = 50
6th number = 50 ÷\div 2 = 25


Therefore, the next 2 numbers are 50 and 25.

Question

These numbers form a pattern.

1 , 2 , 4 , 8 , ? , ?


The next 2 numbers in the pattern are:

Worked Solution

The next number in the pattern is found by doubling the previous number.
Starting number = 1
2nd number = 1 ×\times 2 = 2
3rd number = 2 ×\times 2 = 4
4th number = 4 ×\times 2 = 8
5th number = 8 ×\times 2 = 16
6th number = 16 ×\times 2 = 32


Therefore, the next 2 numbers are 16 and 32.
