Answer:
The sum is approximately 42.56
Step-by-step explanation:
Notice that you are dealing with a series whose first term is :

followed by sum of terms of the form:

and this is a geometric sequence of common ratio given by:
(the value you need to multiply one term of the geometric sequence in order to find the following one)
Then, we can use the general formula for a partial sum of a geometric sequence for these last 5 terms for which m=5, the common ratio r =
, and
= 3:

So, the total sum of the six terms is:
Total sum = 3 +39.5625 = 42.5625
which can be rounded to hundredth: 42.56
