WebSo this is indeed an arithmetical sum. But this summation starts at n = 15, not at n = 1, and the summation formula applies to sums starting at n = 1. So how can I work with this summation? By using a little trick: The quickest way to find the value of this sum is to find the 14 th and 47 th partial sums, and then subtract the 14 th from the 47 th.
