Question

I need help with my math

Answer 1

Given data:'

The second term is 14.

The third term is 28.

The common ratio is,

$\begin{gathered} r=\frac{28}{14} \\ =2 \end{gathered}$

The first term is,

$\begin{gathered} a=\frac{14}{2} \\ =7 \end{gathered}$

The fourth term is,

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

The seventh term is,

$\begin{gathered} a_7=224\times2 \\ =448 \end{gathered}$

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