Best ResponseYou've already chosen the best response.0Geometric progression follows the rule a, ar, ar^2, ar^3 and so on comparing first two terms, you can find out that r = 3 you can see that since the first term (a) = 2, the possible answers can be B or C Since you have found r, you know that the answer is C
