Find the sum of the infinite geometric series. 4 + 2 + 1 + 1/2 + Write your answer as an integer or a fraction in simplest form. ______

Identify Terms: Identify the first term (a_1) and the common ratio (r) of the geometric series. The first term a_1 is the first number in the series, which is 4. To find the common ratio r, we divide the second term by the first term. r = a_2/a_1 = 2/4 = 1/2Calculate Common Ratio: Use the formula for the sum of an infinite geometric series, which is S = a_1 / (1 - r), where S is the sum, a_1 is the first term, and r is the common ratio. We have a_1 = 4 and r = 1/2. Now, plug these values into the formula to find the sum. S = 4 / (1 - 1/2)Use Sum Formula: Simplify the expression to find the sum. S = 4 / (1/2) S = 4 * (2/1) S = 8

Identify Terms: Identify the first term $a_1$ and the common ratio $r$ of the geometric series. $\newline$ The first term $a_1$ is the first number in the series, which is $4$ . $\newline$ To find the common ratio $r$ , we divide the second term by the first term. $\newline$ $r = \frac{a_2}{a_1} = \frac{2}{4} = \frac{1}{2}$
Calculate Common Ratio: Use the formula for the sum of an infinite geometric series, which is $S = \frac{a_1}{1 - r}$ , where $S$ is the sum, $a_1$ is the first term, and $r$ is the common ratio. $\newline$ We have $a_1 = 4$ and $r = \frac{1}{2}$ . $\newline$ Now, plug these values into the formula to find the sum. $\newline$ $S = \frac{4}{1 - \frac{1}{2}}$
Use Sum Formula: Simplify the expression to find the sum. $\newline$ $S = \frac{4}{\frac{1}{2}}$ $\newline$ $S = 4 \times \frac{2}{1}$ $\newline$ $S = 8$
