Question

4, 16, 64, 256, 1,024, . . .

This sequence has a

common difference of 4
common ratio of 4
common difference of 1/4
common ratio of 1/4

Answer 1

4.4=16
16.4=64
64.4=256
.
.

so the answer is common ratio of 4

Answer 2

Option 2nd is correct

common ratio of 4

Explanation:

Common ratio defined as:

For a geometric series the ratio of a term to the previous term,

As per the statement:

Given the sequence:

4, 16, 64, 256, 1,024, . . .

This is a geometric sequence.

Common ratio = 4

Since,

`(16)/(4)=4`,

`(64)/(16)=4`,

`(256)/(64)=4` and so on...

Therefore, the given sequence has a common ratio of 4
