Q:
# Is this a geometric sequence: 256, 192, 144, 108.

Accepted Solution

A:

Answer:YesStep-by-step explanation:For GP, Tn = ar^(n-1), where a = first term and r = common ratio, again, r = Tn/Tn-1 All we will do is to verify if T2/T1 = T3/T2 192/256 = 144/192 0.75 = 0.75

Conclusion: As T2/T1 = T3/T2 which is 0.75 = 0.75, therefore, It is a Geometric Progression (GP)

Conclusion: As T2/T1 = T3/T2 which is 0.75 = 0.75, therefore, It is a Geometric Progression (GP)
