Answer:
2,6,18,54
How I got this answer:
Each term after the first is found by multiplying by a fixed, non-zero number called a common ratio.
step by step:
2×3=6
6×3=18
18×3=54
The common ratio is 3.
For this case we have the following expression:
![\frac {3} {4} g = \frac {5} {8}](https://tex.z-dn.net/?f=%5Cfrac%20%7B3%7D%20%7B4%7D%20g%20%3D%20%5Cfrac%20%7B5%7D%20%7B8%7D)
We clear the value of the variable "g", for this:
We multiply by 4 on both sides of the equation:
![4 * \frac {3} {4} g = \frac {5} {8} * 4\\3g = \frac {20} {8}](https://tex.z-dn.net/?f=4%20%2A%20%5Cfrac%20%7B3%7D%20%7B4%7D%20g%20%3D%20%5Cfrac%20%7B5%7D%20%7B8%7D%20%2A%204%5C%5C3g%20%3D%20%5Cfrac%20%7B20%7D%20%7B8%7D)
We divide by 3 on both sides of the equation:
![\frac {3g} {3} = \frac {20} {8 * 3}\\g = \frac {20} {24}](https://tex.z-dn.net/?f=%5Cfrac%20%7B3g%7D%20%7B3%7D%20%3D%20%5Cfrac%20%7B20%7D%20%7B8%20%2A%203%7D%5C%5Cg%20%3D%20%5Cfrac%20%7B20%7D%20%7B24%7D)
We simplify:
![g = \frac {10} {12} = \frac {5} {6}](https://tex.z-dn.net/?f=g%20%3D%20%5Cfrac%20%7B10%7D%20%7B12%7D%20%3D%20%5Cfrac%20%7B5%7D%20%7B6%7D)
Answer:
![g = \frac {5} {6}](https://tex.z-dn.net/?f=g%20%3D%20%5Cfrac%20%7B5%7D%20%7B6%7D)
