first let's find the 50th term. 

the "zeroth" term would be 16 - 3 = 13, meaning the 50th term would be 3(50) + 13 = 163. 

 

\(S_n = \frac{n(a_1 + a_n)}{2}\) where \(a_1\) is the first term and \(a_n\) is the last term of the sum you're finding.

\(S_{50} = \frac{50(16 + 163)}{2}\)

\(S_{50} = 25(179)\)

\(S_{50} = 4475\)

 

tell me if I did anything wrong :)
