Question

Which expression represents the second partial sum for

Answer 1

Answer:

$S_{2} = 3\cdot \left(\frac{1}{2} \right)^{0} + 3\cdot \left(\frac{1}{2} \right)^{1}$

Step-by-step explanation:

The first partial sum is:

$S_{1} = 3\cdot \left(\frac{1}{2} \right)^{0}$

The second partial sum is:

$S_{2} = 3\cdot \left(\frac{1}{2} \right)^{0} + 3\cdot \left(\frac{1}{2} \right)^{1}$

Which represents the option A.
