Answer 4

what u think is it geometric or arithmatic series


\(\large \begin{align} \color{black}{
128, 32, 8, 2, ... \hspace{.33em}\\~\\
}\end{align}\)

note that for arithmatic series

second term-first term=third term-second term=constant

for arithmatic series

second term/first term=third term/second term=constant

so verify this
