Question

find sum -5+(-8)+(-11)+.......................+(-230)​

Answer 1

using the formula :-

(n/2)( first number + last number )= sum where "n" is the number of integers.

Answer 2

Answer:

Step-by-step explanation:

the answer can be solved by sum of n terms terms in A P formula

S=n/2(2a+(n-1)d)

where

d=common difference

a= first term

n= total terms

here a=-5,d=-3,n=76

s=76/2((2x-5)+(76-1)-3)

s=-8930
