Answer:

3

Step-by-step explanation:

The formula for the sum of an infinite geometric series is

\frac{a}{1-r}

Where a is the first term and r is the common ratio. We can see that the first term is 2, and to find the common ratio, we can divide a term by the one before it. We can get:

\frac{\frac{2}{3}}{2} =\frac{2}{3} *\frac{1}{2}=\frac{1}{3}

Now, we have all the values need to evaluate the formula. We can plug them in:

\frac{2}{1-\frac{1}{3} } \\\frac{2}{\frac{2}{3} } \\2*\frac{3}{2}\\3
