Given data:'

The second term is 14.

The third term is 28.

The common ratio is,


\begin{gathered} r=(28)/(14) \\ =2 \end{gathered}

The first term is,


\begin{gathered} a=(14)/(2) \\ =7 \end{gathered}

The fourth term is,


\begin{gathered} a_4=a_3* r \\ =(28)(2) \\ =56 \end{gathered}

The seventh term is,


\begin{gathered} a_7=224*2 \\ =448 \end{gathered}

Thus, the series is 7, 14, 28, 56, 112, 224, 448, and 896.
