Given n 2 the 25th term of Set R 25n 25 25 2 25 75. Given n 2 the 24th term of Set S n 23 2 23 25 and two times that 24th term is 50. 11. The correct answer is C . There s no need to calculate either quantity and you can cancel the product st from both columns. To make the comparison observe the place-value shifts from the decimal number . In Column A the decimal point shifts 3 places left 9 300 and 3 places right .0093 so the quantity is equivalent to . You can now see that Quantity B which is is the same as Quantity A. 12.
