2. -191

3. 48

Answer 2

Given :

1. The successor of the largest negative integer is ________ .

2. The predecessor of -190 is ________ .

3. 30 + (-12) - (-18) + 12 = _______ .

To find : blank = ?

Solution :

Since the largest negative integer = $-1$

Successor means when the given number is added with 1, we get successor of it.

So, Successor of -1 = $-1+1=0$

when we subtract 1 from the given number, we get predecessor .

So, Predecessor of -190 = $-190-1=-191$

3. 30 + (-12) - (-18) + 12 = _______

We get :

$30+(-12)-(-18)+12=30-12+18+12=30+18=48$

Hence, 1) 0, 2) -191, 3) 48.
