1)  

 Type the missing number in this sequence:

1,2, Answer: 4,8,16,32


SOLUTION 1 :

First, look for a pattern. Notice how each number is 2 times the previous number:

1,{---}4,8,16,

Multiply 1 by 2 to find the missing number:

1 × 2 = 2


To make the pattern complete, the number 2 must go in the blank space.



2)  

 Type the missing number in this sequence:

1,4,16, Answer: 64,256,1024


SOLUTION 1 :

First, look for a pattern. Notice how each number is 4 times the previous number:

1,416,{----},256,

Multiply 16 by 4 to find the missing number:

16 × 4 = 64


To make the pattern complete, the number 4 must go in the blank space.



3)  

 Type the missing number in this sequence:

3,9,27,81,243 Answer: 729


SOLUTION 1 :

First, look for a pattern. Notice how each number is 3 times the previous number:

392781243{---}

Multiply 27 by 3 to find the missing number:

243 x 3 = 729

To make the pattern complete, the number 3 must go in the blank space.



4)  

 Type the missing number in this sequence:

1, Answer: 4,16,64,256,1024


SOLUTION 1 :

First, look for a pattern. Notice how each number is 4 times the previous number:

1,---------,16,64,256,

Multiply 1 by 4 to find the missing number:

1 × 4 = 4


To make the pattern complete, the number 4 must go in the blank space.



5)  

 Type the missing number in this sequence:

3,9,27, Answer: 81,243


SOLUTION 1 :

First, look for a pattern. Notice how each number is 3 times the previous number:

3927----243

Multiply 27 by 3 to find the missing number:

27 x 3 = 81

To make the pattern complete, the number 3 must go in the blank space.



6)  

 Type the missing number in this sequence:

1,5,25,125,625, Answer: 3125


SOLUTION 1 :
