Find the sum of the first 17 terms of the arithmetic sequence 10, 14, 18, 22, 26...
kari74 [83]
10, 14, 18 ....

notice, we get the next term by simply adding 4 to the current term, thus "4" is the "common difference, and we know that 10 is the first term.

\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;a_1=10\\&#10;d=4\\&#10;n=17&#10;\end{cases}&#10;\\\\\\&#10;a_{17}=10+(17-1)(4)\implies a_{17}=10+(16)(4)&#10;\\\\\\&#10;a_{17}=10+64\implies a_{17}=74\\\\&#10;-------------------------------

\bf \textit{ sum of a finite 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;a_1=10\\&#10;a_{17}=74\\&#10;n=17&#10;\end{cases}&#10;\\\\\\&#10;S_{17}=\cfrac{17(10+74)}{2}\implies S_{17}=\cfrac{17(84)}{2}\implies S_{17}=714
