Best ResponseYou've already chosen the best response.0Well, in a geometric series you are basically multiplying things over and over again. So if your first term is 6 and your common ratio is 4 that basically means that your geometric sequence is{6,6*4,6*4*4,6*4*4*4,...}. Now, since we know that it's only 7 terms long we can just follow that process until we have 7 terms in the sequence (the last term you will get is 24576). Once you have the sequence you just need to add up all the terms and you'll get the solution.
