set up a force equation for each block individually. for example ...

tension, $\displaystyle T_1$ , in the last string is the net force on $\displaystyle m_1$ ...

$\displaystyle \displaystyle T_1 = m_1 a = m_1 \cdot \frac{F}{m_1+m_2+m_3}$ **Does this tension equation refer to the far left string when you say "in the last string"?**
