Let a₁, a₂, a₃, ..., a_n, ... be a sequence of positive numbers, where a₁=1, and a_n+1= a_n + 4. Which of the following represents the nth term in the sequence? 4n - 3 4n - 1 4n 4n + 1 4n + 4 1 Right! The student got this item correct. 2 Sorry, that was incorrect. The sequence given in the problem started with 1 and had a common difference of 4. That sequence is: 1, 5, 9, 13 . . . A good approach to solving these kinds of problems is to generate the sequence and then test your rule against it. The student probably didn't generate the sequence first. 3 Sorry, that was incorrect. The sequence given in the problem started with 1 and had a common difference of 4.

Could be that the + 4 is taken from the recursive rule in the problem. ExplicitArithmetic RecursiveRuleArithmetic
