Question
If m is a whole number, then $2m$ denotes a multiple of $2$.

Answer

Given, m is a whole number.
Put $m = 0, 1, 2, 3, … 2m $
$= 2 \times 0 = 0, 2m $
$= 2 \times 1 = 2 2m $
$= 2 \times 2 = 4, 2m $
$= 2 \times 3 = 6$
Clearly, $2m$ is the multiple of $2.$
So, multiples of $2$ are $2, 4, 6, …$
Hence, the statement is true.
