use the sequence to answer the questions.
2.5, 6, 9.5, 13, 16.5,

(a) what is the common difference?

(b) what is the recursive rule for the sequence?

So we want to know what is the A) common difference  and B) what is the recursive rule in the given sequence: 2.5, 6, 9.5, 13, 16.5, 20, A) the common difference is: 6-2.5=3.5, 9.5-6=3.5, 13-9.5=3.5...and so on, so the common difference d is d=3.5. B) the recursive rule is a
