# how to manipulate font properties of text above overbracket

How can I change the font properties (e.g. size, style, spacing etc) of text above a overbracket in an equation?

For example:

\overbrace{10000r^{n}-750\left(\frac{1-r^{n}}{1-r}\right)}^\text{expression for any year}

I want to change the font size of the sentence expression for any year to become larger.
