Question

What expression shows the relationship between the value of any term and n, its position in the sequence for the given sequence? 3, 5, 7, 9, 11, ...

Answer 1

B) 2n + 1

Explanation:

Each term increases by 2 units so the common difference is 2. Then plug in 1 into the equations that have a slope of 2 and see if you get 3 out. You do for 2n + 1.
