    \displaystyle\text{PV}=\sum_{i=0}^{\infty}\left[\frac{531.90+130.29\cdot i}{1.1093^i}\right]

    \displaystyle\Rightarrow\text{PV}=\sum_{i=0}^{\inf  ty}\left[\frac{531.90}{1.1093^i}+\frac{130.29\cdot i}{1.1093^i}\right]

    \displaystyle\Rightarrow\text{PV}=531.90\cdot\sum_  {i=0}^{\infty}\left[\frac{1}{1.1093}\right]^i+\sum_{i=0}^{\infty}\left[\frac{130.29\cdot i}{1.1093^i}\right]
