Question

the sum of (-5)+(-8)+(-11)+___+(-230) will be (1) -8730 (2) -8830 (3) -8930​

Answer 1

Answer:

(3)-8930

Step-by-step explanation:

a=-5

d=-8-(-5)

=-8+5

=-3

an=-230

an=a+(n-1)d

-230= -5+(n-1)-3

-225=(n-1)-3

n-1= 75

n=76

Sn=n/2[a+an]

= 76/2[-5-230]

=38(-235)

=-8930

Option 3
