Find an explicit rule for the geometric sequence using subscript notation. use a calculator and round your answers to the nearest tenth if necessary.

the third term of the sequence is 170. the fifth term is 108.8.

The formula for nth term is given as

Step-by-step explanation:

Here, 3rd term in the geometric sequence  =  170

The 5th term in the sequence = 108.8

Let the first term in the sequence = a

Let the common ratio of the sequence = r

Now by the Geometric Sequence:

⇒ From above general term:  

⇒

Dividing both the the equations, we get:

or,

Hence, the common ratio r  = 0.8

Now,

⇒ a =  265.625, r = 0.8

So, the formula for nth term is given as
