Answer:

[tex]S_{13}[/tex] = 403

Step-by-step explanation:

the sum to n terms of an arithmetic series is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] (a + l) ← a is the first term and l the last term

here a = - 5 and l = 67 , then

[tex]S_{13}[/tex] = [tex]\frac{13}{2}[/tex] (- 5 + 67) = 6.5 × 62 = 403
