Please help I don’t really understand how to go about it.

\bf \textit{sum of an arithmetic sequence}&#10;\\\\&#10;S_n=\cfrac{n(a_1+a_n)}{2}\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;----------\\&#10;S_n=795\\&#10;a_1=102\\&#10;a_n=57&#10;\end{cases}&#10;\\\\\\&#10;795=\cfrac{n(102+57)}{2}\implies 1590=159n&#10;\\\\\\&#10;\cfrac{1590}{159}=n\implies 10=n\\\\&#10;-------------------------------

so the nth term is really the 10th term, and we know that's 57, thus

\bf n^{th}\textit{ term of an arithmetic sequence}&#10;\\\\&#10;a_n=a_1+(n-1)d\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;d=\textit{common difference}\\&#10;----------\\&#10;n=10\\&#10;a_{10}=57\\&#10;a_1=102&#10;\end{cases}&#10;\\\\\\&#10;57=102+(10-1)d\implies 57=102+9d\implies -45=9d&#10;\\\\\\&#10;\cfrac{-45}{9}=d\implies -5=d

so, that's the common difference... .so you'd surely know what the 3rd term is, notice the first one is 102.
