  Read the following SAT test question and then click on a button to select your answer.8,a,14,b,20, ...

  The first term of the sequence above is8. Which of the following could be the formula for finding then thterm of this sequence for any positive integern?

  (A)(2 times n) + 6

  (B)(3 times n + 5)

  (C)(5 times n) + 3

  (D)(6 times n) + 2

  (E)(6 times n) + 5

  The correct answer is B

  Explanation

  You do not know the value of thesecondterm or thefourthterm of the sequence, but you do know the values of thefirst,third, andfifthterms. The correct formula must give8as the value of thefirstterm,14as the value of thethirdterm, and20as the value of thefifthterm. Choice E,(6 times n) + 5, gives11, not8, as the value of thefirstterm. Choice A,(2 times n) + 6, gives12, not14, as the value of thethirdterm. Choice C,(5 times n) + 3, gives18, not14, as the value of thethirdterm. Choice D,(6 times n) + 2, gives20, not14, as the value of thethirdterm. This leaves choice B,(3 times n + 5), which gives the correct values for thefirst,third, andfifthterms of the sequence.
