Find the sum of the first 7 terms in the geometric series 1024+512+256

Answer: 2032

Step-by-step explanation:

7. 1024

6. 512

5. 256

4. 128

3. 64

2. 32

1. 16

I know this because half of 1024 is 512, half of 512 is 256, therefore, it continues to be divided by 2.

Add them all or use the formula.
