Answer: here I hope this helps
Step-by-step explanation: To determine if the sequence is geometric, we find the ratio of the consecutive terms shown.
Find the ratio of the consecutive terms. 4,8428,168216,3216232,6432264,128642128,…
The sequence is geometric. The common ratio is r=2.
Find the ratio of the consecutive terms. −2,6−2−36,−126−2−12,36−12−336,−7236−2−72,216−72−3216,…
The sequence is not geometric. There is no common ratio.
27,9,3,1,13,19,…
Find the ratio of the consecutive terms. 927133913131313113191313
The sequence is geometric. The common ratio is r=13.
