Answer:
13.5
Step-by-step explanation:
2/3=9/x
2x=9*3
2x=27
x=27÷2
x=13.5
1 1/4-3/4=2/4
1 1/3 - 3/4=7/12
7/8 - 3/4=1/8
then add 7/12+2/4+1/8= 1 5/24
Based on <em>ratio</em> criterion and definition of <em>geometric</em> series we conclude that the<em> geometric</em> series 1/5 + 1/20 + 1/80 + 1/320 + ... is convergent.
<h3>How to determine the convergence of a geometric series</h3>
<em>Geometric</em> series are <em>discrete</em> formulas of the form
, where a and r are real numbers, and n and b are <em>natural</em> numbers. According to the <em>ratio</em> criterion, a <em>geometric</em> series is convergent if and only if |r| ≤ 1.
In accordance to this information, we conclude that the geometric series 1/5 + 1/20 + 1/80 + 1/320 + ... is convergent.
