Answer:
1536
Step-by-step explanation:
Given : A geometric sequence 0.75, 1.5, 3, 6, . . .
To Find:Find the 12th term
Solution:
0.75, 1.5, 3, 6, . . .
First term =a = 0.75
Common difference = 
nth term of G.P. = 
Where a = First term = 0.75
r = common difference = 2
Substitute n = 12



Hence the 12th term in the geometric sequence. 0.75, 1.5, 3, 6, . . . is 1536.
