Hi aspirant
n=4
a1 = -5.        an= -230

S= n ( a1+an)/2

S= 4( -5-230)/2
S= 2(-235)
S= -470

hi girish,

this is not a career related query but the answer is - 8930.

hope this will help

all the best for your future!!!!!!!!!!!!!

Hello

Given  series 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 = n/2 (a+l)

76/2 (-5-230)

38 * -235 = -8930.

Thus , the sum of your series would be -8930.

Thank you
