Answer:
⇒ Common ratio = 1/2
In-depth explanation:
The question is asking us to find the common ratio of the following geometric sequence:
16, 32, 64, 128
What is the common ratio?
The common ratio is the amount that we multiply or divide by to obtain the next term.
Let's find it.
- 64 ÷ 128 = 1/2
- 32 ÷ 64= 1/2
- 16 ÷ 3 = 1/2
The result is the common ratio, which is 1/2.
∴ Common ratio = 1/2
