Write two integers which are greater than – 4 but their difference is smaller than – 4.

There are number of integers greater than -4, namely

-3, -2, -1, 0, 1, 2, 3, 4, 5, …

By hit and trial method, take -1 and 4. We get,

Difference = -1 – 4

⇒ Difference = -5, which is smaller than -4 [minus & minus = plus; and since, 4 is greater amongst 1 and 4 so the result would have a minus sign]

Similarly, take -2 and 6.

Difference = -2 – 6

⇒ Difference = -8, which is smaller than -4 [minus & minus = plus; and since, 6 is greater amongst 2 and 6 so the result would have a minus sign]

Thus, -1 and 4 are one of such pair of integers.
