Consider this sequence: -81, -54, -36, -24, … .
geometric or not ?
common ratio of terms ? 2/3 ...-(2/3)

Respuesta :

apologiabiology
if it is geometric then
if the terms are a,b,c,d then
b/a=c/b=d/c
so
-54/-81=-36/-54=-24/-36?
2/3=2/3=2/3

and that is the common ratio

it is geomertic and common ratio is 2/3
