Write four pairs of integers which are at the same distance from $$2$$ on the number line.
$$\bullet$$ From $$2$$, move $$1$$ unit toward right and left. We will reach to 1 and $$3$$.
$$\textbf{Thus, 1 and 3 are at unit distance from 2}$$.
$$\bullet$$ From $$2$$, move $$2$$ units towards right and left. We will reach to $$0$$ and $$4$$
$$\textbf{Thus, 0 and 4 are at 2 unit distance from 2}$$.
$$\bullet$$ From $$2$$, move $$3$$ units towards right and left. We will reach to $$-1$$ and $$5$$
$$\textbf{Thus, -1 and 5 are at 3 units distance from 2}$$.
$$\bullet$$ From $$2$$, move $$4$$ units towards right and left. We will reach to $$-2$$ and $$6$$.
$$\textbf{Thus, -2 and 6 are 4 units away from 3}$$.
$$\therefore$$ $$\textbf{Four pairs of integers which are at the same distance from 2 on the number line are 1 and 3;}$$
$$\textbf{0 and 4; -1 and 5; -2 and 6}$$
