Step-by-step explanation:
We are given the explicit formula
, where n is the term number.
The third climb up would be the third term; this means we replace n with 3:
![a_3=2(\frac{1}{4})^{3-1}\\\\a_3=2(\frac{1}{4})^2=2(\frac{1}{4}\times \frac{1}{4})=2(\frac{1}{16})=\frac{2}{16}=\frac{1}{8}](https://tex.z-dn.net/?f=a_3%3D2%28%5Cfrac%7B1%7D%7B4%7D%29%5E%7B3-1%7D%5C%5C%5C%5Ca_3%3D2%28%5Cfrac%7B1%7D%7B4%7D%29%5E2%3D2%28%5Cfrac%7B1%7D%7B4%7D%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%29%3D2%28%5Cfrac%7B1%7D%7B16%7D%29%3D%5Cfrac%7B2%7D%7B16%7D%3D%5Cfrac%7B1%7D%7B8%7D)
The answer is 12.2
