Answer:
1 is the third term.
Step-by-step explanation:
Geometric sequences have a common ratio. This means a term divided by previous term is the same no matter the choosing of term.
So for example:
![\frac{a_{n}}{a_{n-1}}=\frac{a_{n-1}}{a_{n-2}}=\cdots=\frac{a_4}{a_3}=\frac{a_3}{a_2}=\frac{a_2}{a_1}](https://tex.z-dn.net/?f=%5Cfrac%7Ba_%7Bn%7D%7D%7Ba_%7Bn-1%7D%7D%3D%5Cfrac%7Ba_%7Bn-1%7D%7D%7Ba_%7Bn-2%7D%7D%3D%5Ccdots%3D%5Cfrac%7Ba_4%7D%7Ba_3%7D%3D%5Cfrac%7Ba_3%7D%7Ba_2%7D%3D%5Cfrac%7Ba_2%7D%7Ba_1%7D)
So anyways geometric sequences means you are just multiply the common ratio over and over to generate the next term.
So, the first term is 1/4.
The second term is (-2)(1/4)=-1/2.
The third term is (-2)(-1/2)=1.
