Answer:
Step-by-step explanation:
So generally a geometric sequence can be defined as: 
which is the explicit form. The r, is what each previous term is being multiplied by to get the next value which is evident in the recursive form: 
. Knowing this we can take two values which are "next" to each other to find what r is. In this case I'll just is 1 and 1/4, given these two values we know that: 
, 1*r is just r... so what each term is being multiplied by is 1/4. So let's plug the values into the explicit formula: 
(I didn't put an a_1 value in front, since it's just 1... so it's a bit redundant). Anyways using this formula we simply plug in 5 as n into the equation to find the 5th term:
