Answer:
d
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 5, thus
[tex]S_{11}[/tex] = [tex]\frac{11}{2}[/tex] [ (2 × - 3) + (10 × 5) ]
= 5.5(- 6 + 50)
= 5.5 × 44
= 242 → d
