-3 is the answer hope it's helps to u

Answer 2

Answer:

ANSWER

It is an A.P.,

in which, a=−5,d=−8−(−5)=−3,l=−230

First calculate the number in series.....

l=a+(n−1)d

−230=−5+(n−1)−3

−225=−3n+3

3n=228

n=76.

Now,

Sum of the series =

2

n

(a+l)

76/2(−5−230)

38×−235=−8930.

So, the sum of your series would be −8930.
