Which one of the following options is correct for the given data in the table?
$\begin{array}{|c|c|c|c|c|}\hline\text{Iteration (i)} & 0 & 1 & 2 & 3 \\ \hline\text{Input (I)} & 20 & -4 & 10 & 15 \\ \hline text{Output } X & 20 & 16 & 26 & 41 \\ \hline \text{Output } Y & 20 & -80 & -800 & -12000 \\
\hline \end{array}$
- $X(i)=X(i-1)+I(i) ; \quad Y(i)=Y(i-1) I(i) ; \quad i>0$
- $X(i)=X(i-1) I(i) ; \quad Y(i)=Y(i-1)+I(i) ; \quad i>0$
- $X(i)=X(i-1) I(i) ; \quad Y(i)=Y(i-1) I(i) ; \quad i>0$
- $X(i)=X(i-1)+I(i) ; \quad Y(i)=Y(i-1) I(i-1) ; \quad i>0$
