E and B Fields (Part 3)

At time $t = 0$ , a particle of mass $m = 1$ and charge $q = +1$ is at rest at the origin in the $xyz$ coordinate system. There are uniform electric and magnetic fields $(\vec{E}$ and $\vec{B})$ throughout all of space.

$\vec{E} = (E_x, E_y, E_z) = (1,2,3) \\ \vec{B} = (B_x, B_y, B_z) = (2,3,1)$

If the spatial coordinates of the particle at time $t = 1$ are $(x_f, y_f, z_f)$ , enter your answer as $x_f + y_f + z_f$
