Alex and Jesse are baking holiday muffins. On day one, they baked five muffins, on day two, they baked 11 muffins, and on day three, they baked 17 muffins. What is the slop for this arithmetic sequence?
A. 1
B. -1
C. -6
D. 6
The slope for an arithmetic sequence can be found by taking the difference between any two terms in the sequence. In this case, we can find the slope by taking the difference between the number of muffins baked on day two and the number baked on day one.
11 - 5 = 6
The slope for this arithmetic sequence is 6, so the answer is $\boxed{\text{(D)}\ 6}$.
