Answer:
a1 = 1/2
r = 3/4
n = 5
Step-by-step explanation:
The given geometric series is:
[tex]\frac{1}{2}+\frac{3}{8}+\frac{9}{32}+\frac{27}{128}+\frac{81}{512}[/tex]
a1 represents the first term of the series. From the above series we can see that the first term is 1/2
r is the common ratio of a geometric series. It can be calculated by dividing any term of the geometric series with its previous terms. For the given series r will be:
[tex]r=\frac{\frac{3}{8} }{\frac{1}{2} }=\frac{3}{4}[/tex]
n represents the number of terms in the series. From the above series we can count the number of terms to be 5.
