Answer
$3i-5j+3k$
Work Step by Step
Let us consider that a vector $v$ is given by: $v=pi+qj+rj$
If a vector $v$ initiates at point $p(x_1,y_1, z_1)$ and terminates at $q(x_2,y_2, z_2)$, then
$v =\lt x_2-x_1, y_2-y_1, z_2-z_1 \gt =(x_2-x_1)i+(y_2-y_1) \ j+(z_2-z_1) k$
Therefore, $v=(4-1)i+(-2-3)j +(1-(-2))k \\=3i-5j+3k$
