Question

2x^3,-4x^5,8x^7 . Find the common ratio

Answer 1

the following GP is

$2x^3$, $-4x^5$,  $8x^7$

$a_{1}$ = $2x^3$

$a_{2}$ = $-4x^5$

$a_{3}$ = $8x^7$

common ratio (r) = $a_{2}$/$a_{1}$ = $-4x^5$/$2x^3$ = -2$x^2$

also , r = $a_{3}$/$a_{2}$ = $8x^7$/$-4x^5$ = -2$x^2$

Therefore, your answer is -2$x^2$.

pls mark as brainliest as it took time to write in math input :D
