The sum of an arithmetic sequence can be found using the formula:

Sum = n/2 * (a + l)

where:
n = number of terms
a = first term
l = last term

In this case, the arithmetic sequence starts with 5 and has a common difference of 1. So, the 17th term would be 5 + (17-1)*1 = 21.

Now, we can substitute these values into the formula:

Sum = 17/2 * (5 + 21) = 221.
