The correct answer is (C). Based on the definition of a geometric series in the 28 x 5 . question, all pairs of successive terms must have the same ratio. Thus, 22 x 2 Cross-multiplying, x 5 16; hence x 5 64. The constant multiple is either 2 or 22. If the second term is 14, the sixth term would be (22)(22)(621) 5 (22)(22)5 5 64. If the second term is 24, the sixth term would be (22)(2)5 5 264. 32. The correct answer is (C). This question requires a bit of intuition. The objective is to minimize the.
