Question

9. The
sum of
of
successor and predicessor
of (-10)​

Answer 1

Answer:

(-20)

Step-by-step explanation:

Successor of (-10) = (-9)

Predecessor of (-10) = (-11)

(-9) + (-11)

=> (-20)

Answer 2

Answer:

let the no. be x

successor = x+1

predecessor = x-1

ATQ

(x+1)+(x-1) = -10

2x = -10

x = -10/2

x = -5

therefore, successor = -5+1 = -4

predecessor = -5-1 = -6
