Solution

Given n is an integer. If we are to consider positive integers, then n = 1,2,3,4,5....

If we consider the expression '3n', we will have $3 \times 1, 3 \times 2, 3 \times 3$ and so on.
These numbers are positive multiples of 3.

Thus for any integer n, 3n is an integral multiple of 3.

Thus, 3n will represent an integral multiple of 3.
