I saw that the first two terms of the sum were incorrect (the summation appeared to be pulling the first two terms using k = 1 and k = 1 instead of k = 1 and k = 2), but would fix itself for later indices.
Here’s the link to the initial activity where I noticed the index issue:
Here’s the link to the second activity which I used to troubleshoot the error:
Thanks!
