Question

Match the items of Column I with that of Column II:

Answer 1

Correct option is A. 1,9,11,15,21

$$1)$$ Two integers whose sum is zero are called additive inverses of each other

So, additive inverse of $$+2 = -2$$

$$\textbf{Hence, for 1) correct match is b)}$$

$$2)$$ We know that, on the number line, negative integers decrease from $$-1 , -2$$… and so on from left of $$0$$

That is, $$-1 > -2 > -3 > -4$$…

So, greatest negative integer is $$-1$$

$$\textbf{Hence, for 2) correct match is e)}$$

$$3)$$ We know that, on the number line, negative integers decrease from $$-1 , -2$$… and so on from left to right from $$0$$

That is, $$-1 > -2 > -3 > -4$$…

So, greatest even negative integer is $$-2$$

$$\textbf{Hence, for 3) correct match is b)}$$

$$4)$$ We know that, on the number line, integers decrease from $$0, -1, -2$$… and so on from left to right from $$0$$

So, $$0$$ is the smallest integer greater than every negative integer.

$$\textbf{Hence, for 4) correct match is a)}$$

$$5)$$ Predecessor is the number that precedes or comes before the given number and is found by subtracting $$1$$ from

the given number.

Predecessor of $$-1 = -1 -1$$

$$= -2$$

Successor is the number that succeeds or comes after the given number and is found by adding $$1$$ to the given

number.

Successor of $$-1 = -1 + 1$$

$$= 0$$

So, Sum of predecessor and successor of $$-1 = -2 + 0$$

$$= -2$$

$$\textbf{Hence, for 5) correct match is b)}$$
