Question

What is the 12th term of the sequence 3,6,12,24....

Answer 1

The answer to this is:

6,144

Answer 2

$a_{0}$=3

r=common ratio: 12/6=2; 6/3=2

r=2, $a_{n}$=$2^{n-1}$*3

plug in 12 for n:

$a_{12}$=$2^{12-1}$*3

$a_{12}$=$2^{11}$*3

$a_{12}$=2048*3

$a_{12}$=6144

The twelfth term in the sequence is 6144
