Question

Find an explicit formula for the geometric sequence 12, 24, 48, 96, .... b(n)=

Answer 1

Answer:

b(n)= 12 x $2^{n-1}$

Step-by-step explanation:

Answer 2

Answer:

B(n)=2

Step-by-step explanation:

12*2=24

24*2=48

48*2=96

96*2=192

SO the common ration in this geometric sequence is 2
