I found $2.5$ $2.5$ volts but check my method!

Explanation:

Voltage is energy/charge or $\frac{joule}{coulomb}$ $"joule"/"coulomb"$ (basically equat to the energy carried by each charge of one coulomb).
In our case we have:
$V_{1} = \frac{12}{2} = 6$ $V_1=12/2=6$ volts
$V_{2} = \frac{7}{2}$ $V_2=7/2$ volts
The potential difference should be:
$V_{1} - V_{2} = 6 - \frac{7}{2} = \frac{12 - 7}{2} = \frac{5}{2} = 2.5$ $V_1-V_2=6-7/2=(12-7)/2=5/2=2.5$ volts
