Question 1197284
<br>
The 5th term is the 3rd term, multiplied by the common ratio twice. Divide the given 5th term by the given 3rd term and take the square root of the result to find the common ratio.<br>
Then to find the 12th term, multiply the given 5th term by the common ratio 7 times.<br>
Note that the given information only gives us the square of the common ratio, so that common ratio might be either positive or negative.  Since the given 5th term is positive and you are multiplying by the common ratio an odd number of times, the 12th term could be either positive or negative.<br>
