Find the sum of the finite arithmetic sequence.Sum of the integers from -100 to 30.
Added by Elizabeth L.
Step 1
The formula for finding the number of terms in an arithmetic sequence is: n = (last term - first term)/common difference + 1 In this case, the first term is -100, the last term is 30, and the common difference is 1 (since we're counting by ones). So: n = (30 - Show more…
