Question

What is the common ratio between successive terms in the sequence? 2,-4, 8, -16, 32, 64,. O-2 O6 O6 O2

Answer 1

a ratio is always a division

We check it by dividing the next number by the previous one

$\begin{gathered} -\frac{4}{2}=-2 \\ \frac{8}{-4}=-2 \\ -\frac{16}{8}=-2 \end{gathered}$

we can continue but is the same number

so the common ratio is -2
