_________________________________________________________

Dados;

A1 → 50

N → 952

R → a2-a1 → 57-50 = 7

_________________________________________________________

An=a1+(n-1)·r

a952=50+(952-1)·7

a952=50+951·7

a952=50+6657

a952=6707

_________________________________________________________

$\textit{Sn}=\frac{\mathrm{(A1+An).n}}{\mathrm{2} }$

$\textit{S952}=\frac{\mathrm{(50+6707).952}}{\mathrm{2} }$

$\textit{S952}=\frac{\mathrm{6757.952}}{\mathrm{2}}$

$\textit{S952}=\frac{\mathrm{6432664}}{\mathrm{2}}$

$\mathbf{S952}=\boxed{3216332}$
