Question

Find the next number in the number sequence 1,2,4,8,16,...

A) 24
B) 12
C) 20
D) 32

Answer 1

option D i.e 32

Explanation:

The common ratio of the sequence

`(2)/(1) = (4)/(2) = (8)/(4) = (16)/(8) = 2`

Therefore, the next no. is given by

`(x)/(16) = 2`

`x = 16 * 2 = 32`

Answer 2

D.

Explanation:

To get from 1 to 2 you multiply by 2.

To get from 2 to 4 you multiply by 2.

Notice how each number is multiplied by 2? Now try multiplying 16 times 2 which would be 32.
