Question

the sum of integers between -4 and 5 is​

Answer 1

Answer:

-4+5=1

We  subtract and put sign of the greater digit ,here 5.

Answer 2

The sum of integers between -4 and 5 is 4.

Given,

Integers between -4 and 5.

To Find,

The sum of integers between -4 and 5.

Solution,

The integers between -4 and 5 will form an A.P, where

a = -3

d = 1

n = 8

aₙ = 4

Now, the formula for calculating the sum of terms in A.P is

Sₙ = n/a(a+aₙ)

where n is the number of terms, a is the first term, and aₙ is the nth term.

Sₙ = 8/2(-3+4)

Sₙ = 4(1) = 4

Hence, the sum of integers between -4 and 5 is 4.
