Margin of error for this interval?

I know the answer, but was hoping someone could explain to me the formula of how they got it?

A medical researcher measured the pulse rates (beats per minute) of a sample of randomly selected adults and found the following student's T-based confidence interval: with 95.00% confidence, 65.682904 < u(Pulse) < 70.623608

What's the margin of error for this interval?

The answer is 2.5, but I would like to know how you come up with that?
