Question

The sum of four consecutive integers is equal to -2 Find the integers: The first (smallest) integer =The second infeger = The third integer = The fourth (largest) integer =

Answer 1

let the four integers are,

a -1 , a , a + 1 , a + 2

so the sum is = -2

(a-1) + a + (a+1) + (a+ 2) = -2

4a + 2 = -2

4a = -2 - 2

4a = -4

a = -1

The first (smallest) integer = a-1 = -1 -1 = -2

The second infeger = a = - 1

The third integer = a + 1 = -1 + 1 = 0

The fourth (largest) integer =​a+2 = -1 +2 = 1
